The boundary of the object is an important feature for an image. Because of the influence of the noise the edge feature extraction is a basic and difficult problem. In order to restrain the noise of background
improve the edge accuracy of detection
this paper presents an edge feature extraction method for image by the multiscale characteristic of wavelet transform. Using the method of mutual energy cross for edge features in variety of scale and accuracy
this method can restrain noise and recognize edge. Simulations show this method is valid.
