Revision history [back]

Hi there! I try to explain my problem.. I've an image of wood beam where I've to identify the scratches and flaws contained in. I've attached a picture to describe my problem. I've to identify the scratches surrounded by squares. The rectangles in picture were added by hand, just to illustrate my purposes. Can you suggest me some algorithms, procedures or tricks that I can adopt for my goal? I'm new to the computer vision subject and I just know the basis of opencv, so I dunno what kind of algorithms are better for me.. Thank you for the patience and the suggestions! Nikolaj

Note : please don't upload such a big file or give a link to image. i think there is some users have a limited internet access like me :)
