Abstract

It is important for medicine cell image to detect edge and trace contour In the process of recognition. The method of equilibrium is used to improve the contrast between the target and the background for giving prominence to the target at the beginning in this paper. Then edges in the image are detected with Canny operator, followed by edge figures processing that utilizes fundamental transform processing in mathematical morphology. Finally, it makes use of eightdirection chain code searching algorithm to trace contour, and carry on vectorization to the traced contour by using improved variable-step-length algorithm in order to keep and recognize cells further. Better experimental results are obtained by utilizing this method on edge detection and contour tracing of cell images.
