| Abstract: | In this paper, a new method of multi - scale edge detection of image signal is presented based on lifting wavelet. The results show us that the method can be used to many kind of biorthogonal wavelets with the advatages of fast speed and higher precision. According to the features and requirements of flutter test signal, the method for edge detection is used to pickup the major information of signal image, and a new technique is brought out for the flutter boundary prediction. |
