An Image Edge Detection Algorithm Based on the Wavelet Transform

Xie Mei;Gu Deren(Dept.of Electronic Engineering,UEST of China Chensgdu 610051)  
A new method which is used to extract features of the image is introduced in this paper.The method is based on the wavelet transform which provides a multiscale analysis of the image.It provides information of the image boundaries features by determining the local maxima of the wavelet transform at dyadic scale of the image.The examples of a feature extractied image are also shown in the peper.
