Traditional algorithms of image edge detection were analyzed. In order to better detect the image edge information, firstly, non-linear median filter technology of characteristic direction was applied to filter out the Gauss noise; secondly , (3,1) biorthogonal spline wavelet was used as the primitive wavelet filter, adopting lifting scheme to build the most superior biorthogonal wavelet filter, and applying the superior biorthogonal wavelet to the multiresolution wavelet edge detection; at the… CONTINUE READING
