Introduction of image edge detection technology
Shubin Yang · 2003
Differential cofficient edge detection method?edge detection method based on wavelet and fractal theory and edge detection method based on morphology are introduced . Development of these methods applied in imageedge detection is analysed. Also,their superiority and limitation are given. Analysis proves that,for this illposed problem,it's always main research project in image processing and analysis to quest a simple edge detection algorithm which can slove the harmony of edge detection precision and removing the noise.There are a lot of things to research in this field.
