To the contravention between traditional edge detectors' ability of restrain noise and orientation precision,a detection algorithm based on B-spline wavelet is proposed.Firstly,image edge is detected at multi-scale,and then the edge with only a pixel width is obtained by fusing different scale edges with the muti-scale characteristic of edge information.Computer simulation results show that the proposed method can not only detect image edge precisely,but also effectively restrain noise.Comparing with severa...
