| 摘 要： | Canny算子边缘检测算法简单，具有很好的边缘检测性能，对于噪声污染小的图像能取得较好的效果.但对于噪声较大的图像，传统Canny算法不能在噪声抑制和边缘检测之间达到好的平衡.将小波去噪引入到Canny算法中，有效的抑制了噪声在边缘检测中的影响，提高了检测精度.

| Abstract: | The edge detection method based on canny algorithm is simple,and has high edge-detection capability.It can get pleased results for the images with less noise traditional,but for images noised gravely the method can not get well.So,wavelet denoise is introduced in this paper,and this method can different the edges from noise efficiently. |
