Snow White asked:
I need to extract an object from a jpeg using php, and I think the only way to do it is to group all pixel with the same colors. But those extra pixels (which I think are noise), I can’t extract the picture correctly. I’m not sure of what function to use.. Please help! Thanks in advance.

It sounds like what you are trying to do is too complicated with php (and gd). I think you need to use a separate photo editing program like photoshop and work with it there. Also the ‘noise’ you are talking about sounds like anti-aliasing around the object.
