UCLDH Advanced Imaging Consultants

By Melissa M Terras, on 21 July 2016

UCL Centre for Digital Humanities are pleased to announce that we now have capacity to offer Reflectance Transformation Imaging and Spectral Imaging services from our Multi-Modal Digitisation Suite research facility based in central London.

Reflectance Transformation Imaging (RTI), also known as Polynomial Texture Mapping (PTM), is a high-resolution, non-invasive and non-destructive imaging technique for documenting fine surface details. Unlike conventional photographs, images created using the RTI capture method can be virtually relit. The direction of the light source can be moved around in real time to give 3D appearance to surface shapes for systematic inspection of fine surface details.

Spectral Imaging is a high-resolution, non-invasive and non-destructive form of computational photography that can disclose features of the object that are invisible to the naked eye in natural light, and can enhance faded writings, reveal palimpsest and under-drawings, as well as aiding in pigments, binders and other materials identification. Spectral imaging helps clarify and support research, scholarly and other goals. The UCL state-of-the-technology spectral imaging system can be applied to documents and manuscripts, polychrome artworks, and a range of archaeological and heritage objects.

The kinds of material we can handle and are suitable for specialist imaging include:
• Documents, manuscripts, maps
• Artworks and other painted objects
• Coins, medals, jewellery
• Other objects bearing fine details such as seals and impressed sealings, cuneiform tablets, as well as inscriptions, carvings, bas-reliefs
• Forensic evidence or any object/surface requiring detailed examination.

A visit to the China Academy of Art, Shanghai Institute of Design

By Simon Mahony, on 21 April 2016

As part of my recent visit to Shanghai, I was honoured to be the guest of the President of the China Academy of Art, Shanghai Institute of Design. The China Academy of Art (CAA) is the premier Art Academy in China and the Shanghai campus is the foremost Design Institute. Aparently the CAA is also the first art university and first graduate school in China.

The Shanghai Zhangjiang Campus is a small one and the main parts of the university are situated at two locations in nearby Hangzhou, both with very distinctive and award winning architecture. The original campus at Nanshan overlooks the famous West Lake and the Xiangshan Central Campus (the largest site) on the outskirts of Hangzhou has become a tourist attraction in its own right and features the Crafts (Folk Art) Museum (which was unfortunately closed on the day I visited but that provides a good excuse for a follow up visit and next time to stay on that campus).

Stephen Robertson Prize Dissertation 2014/2015 – Congratulations to Rachel Yales!

By Melissa M Terras, on 9 January 2016

We’re delighted that the best dissertation from our MA/MSc in Digital Humanities in currently sponsored by Microsoft, in honour of the work of Stephen Robertson. The student prize for the best dissertation in our 2014/2015 cohort has recently been given to Rachel Yales, for her groundbreaking work “Hoisting Anchor: Exploring the Interaction Between Time, Place, Space, and Text in Early Modern American Travel Narratives Using Digital Methodologies.” Her dissertation examines the origins of both the criticism and praise for the adoption of Geographic Information Systems (GIS) in the humanities and social sciences, examining the process by which GIS based Digital Humanities projects have been developed and produced with a proof of concept study. Using Richard Hakluyt’s late 16th Century text “Principal Voyages of the English Nation”, Yales looks at how GIS approaches are especially conducive to the analysis of the travel narrative genre and the creation of imagined knowledge spaces in early modern England and the Americas. Yales is currently working up her dissertation for consideration for journal publication.

We’re also pleased that the first recipient of the Stephen Robertson prize from our 2013/14 cohort, Jin Gao, has recently returned to UCL to undertake a PhD with us, carrying forward her Master’s dissertation work on citation analysis (which has been accepted for journal publication). This student prize allows us to showcase the best of our student work, whilst also celebrating the achievements of our students: well done Jin and Rachel!

Moving Forward Digital Art History – Report from a UCLDH Workshop

By Melissa M Terras, on 8 October 2015

 

People in UCL Art Museum

A day of lively discussion topped off with a visit to UCL Art Museum, so see some of UCL’s own art treasures.

In June 2015, UCLDH hosted an invitation only workshop titled “Moving Forward Digital Art History” at University College London. The aim of the workshop was to explore “digital art history” – a phrase that has become a shorthand reference to the potentially transformative effect that digital technologies hold for the discipline of art history. The latest tools and techniques allow researchers to handle large volumes of digitized images and texts, trace patterns and connections formerly hidden from view, recover the past in virtual environments, and bring the complex intricacies of works of art to light as never before, to name just a few opportunities. We aimed to discuss how art historians acquire the knowledge to explore these new possibilities, explore the state of digital art history in the UK, and identify potential professional development opportunities and strategies, such as summer institutes, to help the field move forward. We’ve had permission to summarise the findings and discussions of the workshop here, to share with the wider community.

The workshop was hosted by Melissa Terras (UCLDH) with assistance from Anne Helmreich (formerly of the Getty Foundation) and had attendees from the The National Gallery; CHArt (Computer and the History of Art), Department of Digital Humanities, King’s College London; Courtauld Institute of Art, London; History of Art Department, University of Oxford; Slade School of Fine Art, UCL; Slade Archive Project, UCL; Department of History of Art, University of Cambridge; UCL Art Museum; The Tate; Department of History of Art, UCL; Paul Mellon Centre for Studies in British Art; Oxford University Museums and Collections; UCL Department of Information Studies; and the Bodleian Library. This interesting mix of practicing art historians from different institutional contexts, those working with art collections, and those using digital methods in humanistic study, made for a lively debate.

The meeting first discussed the state of digital art history in these institutions – and what it meant to be using digital methods in this space, in those institutional contexts – covering a range of useful and related initiatives, such as the Digital Humanities at Oxford Summer School; the London Charter for the Computer-based Visualisation of Cultural Heritage; the CHArt, Computers and the History of Art (est. 1985) conferences; the Paul Mellon Centre’s new online journal, British Art Studies, which will appear this autumn; the Slade Center for Electronic Media in Fine Art; research projects at the National Gallery which investigate digital documentation and data such as the Mellon-funded Raphael research project and IPERION CH, a large EU networking and joint research project that includes developing digital documentation and data; the National Gallery’s contribution to the Getty’s Provenance Index, British Sales, a major online database; developing a new project to make the archives and inventories of major country houses publicly accessible online; the 3D digital reconstruction of the Florentine church of Santa Chiara; and work by various institutions in the development of apps and online systems. The group also discussed persuasive projects that could help articulate the value of digital art history, such as the Cranach Digital Archive, Bosch Research and Conservation project, and Picturing the Netherlandish Canon (with the observation that while this project may seem out of date by today’s standards it was transformative for the scholars involved). Various project themes emerged, including the uniting of disparate collections and archives and facilitation of contributions to these resources; new forms of publishing; and the opening up of collections to make them available for new pathways of investigation and other forms of digital scholarly inquiry.

Is there an interest and appetite for Digital Art History?

The discussions articulated that scholars have a general interest in learning more about how digital resources and tools could advance their research, but don’t want it to come at the cost of displacing art history’s core concern with the original art object or supporting research resources such as paper archives. Art historians clearly see the benefit of using digital technologies to access collections and resource, and there is a sense of urgency regarding the younger generation who may be more prepared to use digital tools than senior colleagues who are not sufficiently trained to frame a useful/significant project.

What potential challenges or barriers are there for d\Digital Art History?

Various challenges were identified and discussed (summarized here briefly – the challenges are legion!) Image copyright issues create limitations on what scholars might be able to do with images in the online environment. Art historians may not know which tools already exist, such as III-F, and how they might use them. There was discussion on the role of computer scientists in joint projects: are art historians prepared to undertake such collaborative work and could this type of collaborative work support art historical research questions? There is a difficulty in finding art historians qualified to teach digital art history or review digital publications/projects; digital projects can be overlooked in state of the field reviews/reviews of earlier scholarship or standard bibliographies. The term digital may be off-putting to some listeners, and it might be preferable to refer to digital art history as “art history now,” or an integrated art history that brings together research inquiry with building digital resources and online publishing. There may be a perception and anxiety that the digital surrogate will replace the interest in the original object at the heart of art history. Concerns exist that resources will be diverted from supporting outstanding work related to existing research repositories, such as paper archives, that are not yet catalogued. The technological needs for digital projects may exceed what academic university departments can provide. The learning curve for mastering new technologies/systems/approaches may be perceived as too steep, particularly if outcomes are not assured. Art historians may not be able to conceive of research questions well suited to available data, and have difficulty in framing questions appropriate for that data. Because art historians don’t know where to start, don’t know what questions to ask, don’t know how to articulate their digital needs, they may not be taking advantage of already existing training opportunities and resources. Digital specialists tend to be grant-supported and migrate from project to project so that teams must be re-assembled and knowledge leaves institutions. Digital projects tend to be one-offs and not designed to be built upon; they also tend to be more expensive and harder to accomplish than “traditional” projects.

How can we move the use of digital methods in Art History forward?

Various potential solutions were mooted in a brain-storming session (it is acknowledged that some are simpler to provide than others!):

  • The community should address the increasing need for open access resource outlets, support current online publications (e.g. British Art Studies, Tate Papers, Nineteenth Century Art Worldwide) while also considering whether new homes for digital scholarship are needed;
  • To encourage more kinds of digital publications that go beyond print, it would be useful to have a sort of toolbox for art historians to demonstrate what is possible;
  • The stimulation and validation of digital scholarship can be accomplished by encouraging reviews of digital projects in the scholarly literature;
  • Digital Humanists should work collaboratively (museums and universities) with professional art history organizations;
  • If postdoctoral fellowships could be created in this area, they could be tied to digital projects such as online publications, creation of new digital resources/repositories, exhibitions;
  • Greater visibility could be brought to the work of scholars who have undertaken digital projects since they are typically powerful advocates for the transformative possibility of the digital and can also demonstrate how digital scholarship can be deeply motivated by the original object;
  • Identify “flag-bearers” willing to promote these approaches within Art History;
  • Undergraduate teaching is needed, whether a dedicated course or a module within a course, that could help students build digital literacy and incorporate these skills into art historical research inquiry;
  • Encourage leaders of digital projects to include fulsome accessible documentation to let others understand/learn how a project was developed and implemented;
  • Encourage digital resources, such as online image collections, to become more open; that is, to allow users broad search pathways so that they can find new patterns in the data or obtain large amounts of data. In short, recognize that content management systems and licensing can influence what researchers can find and use;
  • Support tools such as III-F that allow researchers to bring together images from different repositories and facilitate side by side comparison;
  • DH centers could function as brokers between computer scientists and art historians to foster the cross-pollination of ideas; could also help art historians frame new research questions using already digitized resources; bring in the resources of technologists and designers that can impact the long-term success of a project; and bring together art historians and technologists;
  • A survey of the field could identify which digital projects art historians are using, building upon, what do people like about these projects, why are they continuing to use them.
  • It is necessary, at all stages, to get academic leadership from within Art History, and Art Historical collections, involved and on board, to help establish digital methods as a bona fide approach in Art History.

Conclusions

This was a stimulating discussion, and as you can see we covered a lot of ground that day – although there is a lot ahead of us to be done! There is huge potential in opening up digital methods within the Art Historical context, and we hope (now we have been well met) to continue the discussion and to work together to tackle provision in this area. The day finished up with a visit to the recently refurbished UCL Art Museum – which brought us back to the things that matter most of all in our discussions on using digital methods in art history, the collections, the objects, the artists, and the art.

We’d like to thank UCL Art Museum for having us! Final thanks go to Anne Helmreich from the Getty Foundation who gave permission for her notes to be edited up and shared, and who helped shape the day, and thanks are also due to the workshop attendees for joining in such a helpful debate.

Tutorial: How to Access UCL’s Virtual Private Network Using Linux

By Rudolf Ammann, on 18 September 2015

Tux

Tux, interpreted by the author, ca. 2002

Some of this university’s computational infrastructure is tucked away behind a VPN login: If you’re trying to reach it from the outside, you need to establish a Virtual Private Network connection to get through. This may be more onerous for users of a Linux operating system than it is for those who rely on Microsoft or Apple products, especially since UCL insists that VPN connections may only be established using one particular VPN client, Cisco’s AnyConnect. This client has its problems, but it also comes with a superior FOSS alternative: OpenConnect.

I will discuss the use of the two clients in turn.

AnyConnect

UCL’s How to set up a VPN connection for Linux tutorial offers instructions on how to install the AnyConnect client. The tutorial does not mention that AnyConnect will fail to work when it is run with restricted privileges. Neither does it mention that AnyConnect, when it attempts to establish a VPN connection while running with restricted privileges, is likely to hang indefinitely, consuming all available CPU, flooding all available RAM, and eventually bringing the system to its knees — unless the runaway process is killed in good time.

To work as advertised, AnyConnect needs to run as root or under sudo. So, once the application is installed, open a terminal and launch it by issuing the following command:

$ sudo /opt/cisco/anyconnect/bin/vpnui

Once you’ve entered your sudo password, this command should pop up a dialog with a single ‘Connect to:’ field. Type ‘vpn.ucl.ac.uk’ into this field, but be prepared to deal with further complications, as you may need to lift a block and ignore a warning before AnyConnect will establish a connection with UCL’s VPN.

UCL’s VPN uses what seems like a legitimate SSL certificate issued by Terena:

$ openssl s_client -connect vpn.ucl.ac.uk:443 |& sed -n '/^issuer=/s/.*CN=//p'
TERENA SSL CA

AnyConnect may not recognise this certificate and respond with an error message that reads: ‘Untrusted VPN Server Blocked!’ To work past this barrier, hit the ‘Change Setting…’ button, which will take you to AnyConnect’s Preferences dialog. In that dialog, untick the ‘Block connections to untrusted servers’ option and hit the ‘Close’ button.

Close and restart the application, then type ‘vpn.ucl.ac.uk’ into the ‘Connect to’ field and hit the ‘Connect’ button. This will trigger a warning: ‘Security Warning: Untrusted VPN Server Certificate!’ Ignore this warning and hit the ‘Connect Anyway’ button!

The next dialog will have RemoteAccess pre-entered into the ‘Group’ field. Supply your Username and Password, hit the ‘Connect’ button, and you’re in!

In theory, it should be possible either to export the Terena certificate as a .pem file from the Firefox Certificate Manager or to download it from Terena’s repository and copy it to /opt/.cisco/certificates/ca/, the directory in which AnyConnect stores its certificates. This should cause the software to recognise the certificate and to stop returning error messages. I have not been able to make this work, however, and not for lack of trying.

OpenConnect

The command-line utility OpenConnect offers an alternative to the above procedure.

You will need to install both OpenConnect and cURL. Binaries of both should be available for your distro of choice via the usual package management.

OpenConnect will need to invoke a shell script that is known as a ‘CSD-wrapper‘, which uses cURL to handle the transfer of data with URL syntax.

Copy the following script (which is adapted from here) into a plain text file, save the file as csd-wrapper.sh, and render it executable:

#!/bin/sh
#set -x

platform_version="x86x64"
device_type="Linux-x86"
device_uniqueid="AAAAAAA"

# delete the csdXXXXXX temp files so they don't start piling up
rm -f $1

exec curl \
--globoff \
--insecure \
--user-agent "AnyConnect Linux" \
--header "X-Transcend-Version: 1" \
--header "X-Aggregate-Auth: 1" \
--header "X-AnyConnect-Identifier-Platform: linux" \
--header "X-AnyConnect-Identifier-PlatformVersion: $platform_version" \
--header "X-AnyConnect-Identifier-DeviceType: $device_type" \
--header "X-AnyConnect-Identifier-Device-UniqueID: $uniqueid" \
--cookie "sdesktop=$CSD_TOKEN" \
--data-ascii @- "https://$CSD_HOSTNAME/+CSCOE+/sdesktop/scan.xml" <<END
endpoint.feature="failure";
endpoint.os.version="Linux";
END

Then issue the following command to establish the VPN connection:

$ sudo openconnect vpn.ucl.ac.uk --csd-wrapper /path/to/csd-wrapper.sh

The network should now prompt you for your username and password. Supply those, and you’re in!

Of course, you might object that running OpenConnect under sudo is less than desirable from a security perspective, and you’d be entirely right about that. There’s a workaround available.

Thanks to Emma Cardinal-Richards at UCL’s Information Services Division and to security analyst Dr Name Withheld from W., both of whom provided valuable assistance towards solving this issue!

How well do Google image results represent reality?

By Oliver W Duke-Williams, on 23 June 2015

Much has been written about Sir Tim Hunt’s remarks at the World Conference of Science Journalists in Seoul earlier this month. The debate has developed in a number of directions, including a discussion about the gender representation in images returned by Google’s image search, with a specific example being made of the male-dominated results when using the search term ‘professor’. Writing in The Guardian, Dame Athene Donald observed:

If you think that doesn’t matter, imagine you are a 12-year-old girl trying to get a sense of what the adult professional world is like. If the only images that appear against the search term of “professor” are either elderly white males or cartoons of men in white coats with sticking-up hair, as a girl you are hardly likely to think it is the sort of career aspiration you should be considering.

The representation of ‘professor’ is of course problematic in a number of ways: as well as being shown as male, professors are also shown as sterotypically balding and bespectacled. Similarly stereotype-driven images are de rigeur in children’s literature, as documented by Professor Melissa Terras. A natural response to this observation is to wonder what the gender representation of other jobs looks like through the prism of Google Images. Are they similarly one-sided? For example, although the Women’s World Cup is under way at the time of writing, searching for ‘footballer’ returns an entirely male set of results. As with the case for professors, this would not encourage a girl to think that football is a sport for all.

‘Digital comparison of 19th century plaster casts and original classical sculptures.’

The seminar will be streamed live to our YouTube Channel

Historical casts of classical sculptures can now function as important archaeological records, sometimes containing archaeological information now lost from originals. However, it was not unknown for 19th century plaster craftsmen to doctor their moulds, such that when cast, a damaged sculpture would appear more complete. To determine the type and usefulness of information present in casts, 3D scanning has been conducted at the British Museum and Acropolis Museum of casts and their corresponding originals, of sections of the Parthenon sculptures. The resulting 3D images are now being produced and digitally compared to facilitate interpretation of these objects and their significances.

As always the seminar will be followed by discussion over wine and refrshments.

Hangeul and hanja in domain names

By Chris J Dillon, on 17 June 2015

King Sejong

King Sejong stands in the middle of Sejong St in front of the Sejong Cultural Center in Seoul. Obviously a key historical figure, then. He was behind the creation of the Korean “hangeul” script in the mid-15th Century. It was done scientifically, so that many consonants were pictures of where they are articulated and are systematically related to similar consonants. So ㄱ, g is related to ㅋ, k with the additional dash and to ㄲ, kk by duplication. ㄲ, incidentally, represents a tense k sound which may be unique to the Korean language. The vowels are a system of dots and dashes, and so ㅣ is i and ㅏ is a.

I was in Seoul for the ICANN Variant Issues Project meeting on the Chinese, Japanese and Korean Label Generation Rules (i.e. which characters should be allowed in Top Level labels). China made huge progress early on and Japan has caught up. Korea has not used Chinese characters, “hanja”, much for several decades but is keen to be able to use them for business reasons – .現代 “Hyundai” would be a lot more widely understood in East Asia than the hangeul way of writing it: .현대.

Just before the meeting I had decided to read through the proposed Japanese table and found various things I shan’t trouble you with – I learnt at an early age that linguists’ ideas of “interesting” don’t necessarily correspond with those of non-linguists’. Then I found something of rather greater interest: 卍 and the reverse form. Currently there is no mechanism to stop the use of the reverse form in a domain name. However, it has been referred for a policy decision. The solution may be that it is removed from the table, or an evaluation panel takes on this sort of role.

I’m back from Seoul keen to do a Korean project and have set up a Korean wiki with a colleague at SOAS: Korean Wiki

If you speak or are learning Korean and are based at UCL, I’d love to hear from you.
