Abstract
This paper presents how to split touching blood cells. The algorithm mainly consists of three sub-algorithms; they are Canny edge based segmentation, the algorithm of splitting based on valley edge (weak edges) detection and the algorithm for splitting based on shape information. It first traces blood cell boundaries based on discontinuities, then splits touching parts of blood cells based on slow variations of gray information in touching parts, and finally splits the remaining touching parts, where no gray information can be used, by using morphological mathematics method (e.g. distance map) combining blood cell shape information (information is classified by using fuzzy mathematics). The algorithm can automatically delineate blood cells not only on a simple image (a few blood cells touching) and also on a complex image (many cells touching together). The algorithm has been tested in a laboratory, it works well.
