Abstract
The visual similarity between fonts is determined using visual descriptors of character images in the fonts. A model used to generate the visual descriptors may include a set of letterforms, keypoint locations on each letterform, and detail shapes at zero, one, or more detail areas on the letterform. In some instances, the model may also set forth one or more geometric measurements. Based on the model, a visual descriptor may be generated for a character image from a font by identifying a letterform of the character image, identifying keypoint locations on the character image, and identifying a detail shape at any detail areas on the character image. Additionally, the visual descriptor may include any geometric measurement defined by the model. The visual similarity between two fonts may be determined as a function of the differences between pairs of visual descriptors for the fonts that correspond with the same letterform.
