一个多尺度边缘检测实例，方法是： 1、先对图像进行3个尺度的小波变换； 2、求小波系数的模值及其梯度方向； 3、确定模的极大值，即候选边缘点； 4、通过反变换合成3个尺度的模的极值图像-A multi-scale edge detection example, the method is: 1, first image of the three-scale wavelet transform 2, and the modulus value of wavelet coefficient and its gradient direction 3 to determine the mode of great value, that is, the candidate edge points 4, through the anti-transform-scale synthesis of three-mode images of the extremum
