Abstract
Methods, computer readable media, and apparatuses for font matching are presented. A glyph may be received and processed. The processing of the received glyph may include reducing the glyph, computing bounds associated with the glyph, and normalizing the glyph. The processed glyph may be compared to a repository of image prototypes. The comparison may include determining a distance of the processed glyph from one or more the image prototypes, sorting the determined distances, and selecting one or more of the image prototypes based on the determined distances. Additional techniques may be used to enhance the resolution or accuracy associated with the various methods and algorithms.
