Stephen Krewson

I am a PhD student in the department of English at Yale University, where I research the interplay between progressive education and media across the long nineteenth century.

Projects

For the Medical Heritage Library, I've been working on a two-stage filter for identifying and extracting historical medical illustrations. The results of this process (which uses the Mask-RCNN algorithm for image localization) can be seen on Flickr. Working with the MHL consortium's 260,000+ volumes has enabled me to create visualizations that start to answer some basic questions about how medical publishing was affected by new image-making technology. This zoomable chart shows that the ratio of illustrated to unillustrated pages tripled in London-printed books over the nineteenth century.

A grant from the Yale DH Lab funded development of a prototype for my Illustration Collation tool. In the example, twelve different editions of John Newbery's The Newtonian System of Philosophy Adapted to the Capacities of young Gentlemen and Ladies [...] (1761) are arranged in a grid that allows for common pictorial elements to be aligned in columns. The format shows the emergence or disappearance of visual subjects in a clear, intuitive way. For instance, a hot air ballon first appears in William Magnet's updated London edition of 1794 (and becomes visually sticky, appearing in all subsequent editions).

I am seeking collaborators and funding to add a backend database to Illustration Collation and use deep learning to auto-populate the grid with images for user-uploaded sets of editions.
