| Abstract: | Through the study of the difference between the first-generation wavelet and the second-generation wavelet,the paper researches an approach to edge detection using second generation wavelets.Edge detection based on multi-scale lifting wavelet offset effectively the shortage of traditional edge detection algorithm,and it can restrain the influence of the noise and can improve the edge localization accuracy.Lifting scheme is the new method that construct orthogonal wavelet structure,the paper brings forward a... |
