Abstract
Based on the idea of detecting multiscale edge by Mallat, multiscale edge detection with continous wavelet transform is done. During the calculation of continous wavelet transform, Fourier transform is used.The method of weighted average is given to calculate the modulus on every direction.At last a example is given.
