AN EDGE DETECTION BASED ON IMAGE FUSION ALGORITHM

Abstract

Edge detection is a part of image segmentation. It is important in digital image processing. The canny edge detector in multi-resolution is not suitable because edge detection is done using only one scale. To over-come this problem we can use wavelet transform for edge detection but this method give poor result in noisy image. We can improve this result by the edge detection based on image fusion method. In this method low frequency information is done with canny detector and high frequenecy information is done with wavelet transform. This method is not only removing the noise but also enhance an edge. Keywords: edge detection, wavelet transform, canny operator, denoising algorithms, fusion rule.
