Method and apparatus for determining the font of text in an image

摘要

Systems and methods are provided for automatically determining the font of text in a captured document image. Sequences of turns (left, right, straight) around the boundaries of connected components of black pixels in the captured document image are determined. The probabilities of the sequences of turns have come from a particular font within a library of known fonts can be determined using training set statistics. Using these probabilities, the most probable source font is selected. <IMAGE> <IMAGE>
