The bulk of my research, and my PhD, is at the intersection of computer vision and art history – supervised by Sabine Suesstrunk (IVRL) and Franco Moretti (Digital Humanities).
Aby Warburg’s Bilderatlas and the Pathosformel
Aby Warburg understood that art, passions and emotions are not only portrayed mimetically. Sometimes, they come to us through repeated formulas – most often, formulas of the body – which he christened Pathosformeln. These Pathosformeln move from antiquity to the modern period, in mythological or everyday scenes, from high art to popular book prints. Neither depiction nor symbol, Pathosformeln lie in the Zwischenraum that Warburg identified between semiotic and pritive reactions. His most ambitious project, the Bilderatlas, was unfinished by his death.
My collaborative project with Franco Moretti tries to understand the Pathosformel and its role in the Bilderatlas through computational and formal means. We attempt to operationalise the Pathosformel – that is, to turn it into a sequence of quantitative operations – and in doing so reach a better critical understanding of the Pathosformel itself, as in the disassembling of a clock-mechanism. By reducing the Pathosformel to its bare constituents, viewing them as statistical phenomena, we find a remarkable unity across Warburg’s taxonomy of passion.
Computer Vision in Paintings
In order to do computational, content-based art history with computer vision, we need to know how to build computer vision systems that work on paintings, bas-reliefs, scultpures, and so on. Most – if not all – of the research focus in computer vision has, however, been on photos. Instead of starting from scratch again, I’m interested in trying to use networks, datasets and techniques from photo-based computer vision in paintings. This isn’t just a case of domain transfer, I claim, but of generalisation.
I focus on two problems: pose detection in paintings (for detecting Pathosformeln automatically), and generalisation of photo-based computer-vision models to paintings (including style tranfser).
Gesture in Art, Gesture in Hieroglyphs, Gesture in Psycholinguistics
Psycholinguists such as Adam Kendon and David McNiel propose a great deal of unity between what was previously considered (spoken) language and gesture. Together with Alexandre Loktionov at the Library of Congress, we look at gesture which is both static and purposefully depicted – such as a painting or hieroglyph – seeing how linguistic theory (normally based on ‘live’ gestures) translates (or doesn’t). The examples of Pathosformeln . Furthermore, linguistic models for the development of gesture – combined with Warburg’s theory of Pathosformeln – could form the basis of a formal analysis of pose from paintings, automatically estimated by computer-vision.
Ways of Machine Seeing
John Berger popularised the ideas of Walter Benjamin in his 1972 BBC TV series, Ways of Seeing, where he showed how the way we see art was influenced by material (class, patron, profit, advertising) and technological (photography, reproduction, the ‘detail’ postcard) conditions. The Ways of Seeing group is formed by me, Prof. Alan Blackwell (Cam), Dr. Anne Alexander (Cam) and Prof. Geoff Cox (Aarhus). We seek to update this analysis to computer vision, and more generally, to machine ways of seeing. We organise a yearly workshop in Cambridge called Ways of Machine Seeing.
Artistic Research and Critical Technical Practice
It seems to me that the Digital Humanities, Critical Technical Practice (Philip Agre’s strand of artificial intelligence research) and Artistic Research are the three principal meeting-points of critical theory and technical research – yet they seldom talk to each other. To this end, I’m organising the first ETH-domain summer school on CTP and AR in the digital humanities. Link soon – watch this space – but for more information, contact me directly.
