Cell-edge detection method based on canny algorithm and mathematical morphology

Based on Canny operator and mathematical morphology, a new cell-based method for extracting the edge, being crucial to subsequent target feature extraction and image matching recognition, has been discussed in this paper. The image edge of cell is estimated by the Canny algorithm and then mathematical morphology is used for dilation which filled the fracture of the edge, with that the internal pore of the cell image is filled. Finally, smoothing is operated by mathematical morphology. The experimental results demonstrate clearly that the proposed approach is more superior to the traditional differential operator and Canny edge detection method.
