【Abstract】 This paper proposes a differential extremum based edge detection algorithm in local region. The feature of the algorithm is that the e dge pixel is directly extracted at an edge detection windows. The extracted edge is true, continued. The algorithm is suited to the segment of the image having unsymmetrical light illumination. The segmentation experiment gives satisfactory result.更多还原
