Character width change detection method for stroke extraction

摘要

The present invention relates to a character width change detection method for extracting a stroke. In the prior art, since the calculation is performed on a pixel-by-pixel basis in extracting a stroke by thinning a character image, a calculation amount increases, . According to the present invention, the input character image is detected on a segment-by-segment basis, the junction node is distinguished from the path node, and the width of the path node is detected. The present invention can extract a stroke much faster than the stroke extraction by the conventional thinning method. In particular, by extracting the fixed stroke by accurately extracting the width change, Can be prevented.
