I had done Edge detection using wavelet transform using thus steps changing the image to Gray scale decomposing the image using dwt2(discrete wavelet transform,Haar wavelet filter ) in to horizontal,vertical,diagonal and approximation(detail) further decomposing the horizontal part threshold (global threshold like canny Edge detection ) i got the edge but i got a problem while locating the edge to complete image to mean recovering original image using only the Edges so i need help concerning this either in concept ,mat lab code or references I hope i will get your help soon
A:
Before your transformation to gray scale you could try filtering the image of specific color ranges which may simplify the problem. This is a tactic used to weaken Captchas before sending it off to an OCR like Tesseract
Another tool that may help is a Flood Fill Algorithm.
