The writer analyzed mallat three criteria and introduced the optimized function based on these three criteria , at last found optimized mother wavelet for edge detection . at the end of this chapter single edge searching method based on local maximum is introduced and gained ideal edge image 分析mallat提出的评价边缘检测函数优劣的三个判别函数,利用这三个判别函数列出最优化方程,推导出边缘检测最优小波,最后创造性提出局部最大值单像素边缘搜索法,提取出单像素宽度边缘图像,图像效果达到了满意的效果。
