| 摘 要： | 图像的边缘表现为图像上的不连续性，边缘检测就是检测图像上的不连续点或陡变点。本文根据Mallat多尺度边缘检测原理，提出了一种图像的边缘检测的新算法。与Mallat的多尺度边缘检测算法相比，这个算法具有计算量小的优点。文中给出了应用这个算法对图像进行边缘提取的实例。

| Abstract: | The edge of image is manifested as discontinuity in image,what edge detection means is to doled (in the image ) those discontinuous points or sharp variation points. According to Mallat's mulliscale edge detection principle, a new algorithm on multiscale edge detection is suggested. Compared with Mallat's algorithm on multiscle edge detection, this algorithm has the advantage of low computational complexity. An example is also given by applying this algorithm. |
