我编写的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; -I prepared a multiscale edge detection example, the method is : 1, the first three images scale wavelet transform; 2, wavelet coefficients for the modulus value and gradient direction; 3 to determine the maximum value model, the candidate edge points; 4, through the inverse transform Synthesis of 3 Scale model of the extreme images;
