If you have an image processing related question, provide a representative set of possible input images. Otherwise, you might get a proper solution for the one or two input images you provided, but while testing that solution on your actual data set, you find out "it doesn't work", and possibly post (a lot of) follow-up questions, which could've prevented in the first place. And, don't get upset, when people don't want to further support then.
