Dear All, I have original and binary images attached here. When I binarize original one, I lose many fine cracks. I used imadjust() and histeq() but still not improved. In the Binary image, red colour circles are used to show the the missing fine cracks. Could you please help me to improve it. Sorry it might be a silly question again. Thanks in advance.

just a suggestion,maybe u can try edge detection method?When i load your image to my code for edge detection, i get the image of almost all the edge. Steps i did: 1.Convert to grey image 2.Run sobel edge detection I'm not sure whether this is the best method or not since i'm quite new to matlab but i hope this might provide you with some little hint :D PS:if there's any other better method,i would like to know too xD Thank you
