Approach of Image Edge Detection Based on Wavelet Scale Multiplication

Abstract:

Article Preview

Edge detection is one of the most important techniques in image processing. A new image edge detection approach is presented by wavelet scale multiplication, which has the advantage of magnifying the edge structures and suppressing the noise. The dyadic wavelet transforms at tow adjacent scales are multiplied as product function and image edge is detected by wavelet model maximum. It need not link edge points, realize simply and is usually applied to noisy, low contrast image.
