Taylor Berg-Kirkpatrick, Greg Durrett, and Dan Klein.
Ocular can recognize collections of documents that use historical fonts. The system is unsupervised: you don't need document images that are labeled with human transcriptions in order to learn a particular historical font. Instead, Ocular learns the font directly, straight from the set of input document images you want transcribed.
