Abstract: This paper presents a method to locate and count the cells based on the computer automatic recognition technique. After enhancing the microcell image, we use circular arc algorithm to locate the cells accurately Then the red cells were distinguished from white cells in the image effectively by using their features, after which we recognized and analyzed those cells quantitiyely. Experimental results show the proposed algorithm can locate and distinguish the cells effectively, and also reduce the wrong diagnosis caused by human being. It enhances the diagnosis efficiency and accuracy.
