Abstract
Wavelet transform is a new and good image processing method that well separates different frequency components of an image. This paper mainly discuses image edge detection with the band-pass filtering property of wavelet transformation. After wavelet transforming and edge extracting, an image can be clearly seen in detail. Compared with other image edge extraction methods, such as Roberts operator, Laplacian operator, Sobel operator and Kirsch operator, this method has good extraction effect and is suitable to binary process. This is very useful to medical diagnose and remote sense image recognition.
