In that question, the person asking the question wanted to do the same thing: match an outline (of a star in that case) to be found in images. Three different solutions were outlined there, one by Stephen and two by Image Analyst.

Is not the same , me i have pixels of outline of each region. I like to find pixels that are the same in the list of outline. I have a solution but i like an optimize solution.

Can you post a sample image? I am having trouble visualizing what you're asking.
