Simply speaking. There are some seeds, I take a photo of them, then, I want to group those seeds with a program.

I want to work it out by read the longest length measured parallel and longest width measured vertical, if the picture's format is bmp, I think I can know its size(arithmetic product of length and width) by translate pixel coordinates. I hope it will help me, actually, it's very hard to do. I ask for your help, no matter what advise you give me, thanks.

You can see a sample picture here, http://imagebin.org/150587.
