| Abstract(in English) | Ideally, an OCR system would partition the set of connected black components on a page into subsets representing individual characters. However, this approach is inadequate if some component partially belongs to several touching characters. We present a DP matching-based method that cuts such a component apart, given a hypothetical classification for the leftmost part. Our method produces better quality cuts than well-known methods, particularly in mathematical expressions, where characters are often slanted and may touch in widely varying configurations. A good cut allows single-character recognition techniques to be applied to the cut part and the residual image, in order to judge whether the hypothetical classification was correct. |
