| Abstract: | Edge detection is very useful in computer vision. However, the existing methods of edge detection are sensitive to the impulsive noise. Thus, how to obtain a better edge detection is important. As a new tool, the wavelet transform has been used in signal processing widely. In this paper, based on the double Haar wavelets, a new edge detector is developed. Comparing with the traditional methods, the proposed edge detector can suppress the impulsive noise effectively. |
