摘要
根据Malat的多尺度边界探测的思想,实现了连续小波变换的多尺度边界探测,并用快速Fourier变换作为工具,进行连续小波变换的计算。在计算任意方向的模值时,提出了使用加权平均的方法。给出了算例。
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.
