IMAGE SKELETONIZATION METHOD

摘要

PURPOSE: To increase the processing speed and to improve the precision by causing plural templates to pass on a picture in parallel and determining whether a selected part of the picture can be deleted from the picture or not without conditions based on comparison between each template and the picture. CONSTITUTION: This method consists of the step, where plural templates larger than a window of 3×3 picture elements are caused to pass on the picture in parallel and the step where it is determined without conditions whether a selected part of the picture can be deleted from the picture or not based on each of templates 120 to 350 and the picture. A set of used templates includes different templates 120 to 350, and each template has a specific arrangement between dark picture elements and light picture elements. Thus, the processing speed is increased and the precision is improved.
