Answer 1

It depends how generic the polygons can be. If the edges of the polygon are always parallel to x and y axes, then you could look at pixels in 8-neigborhood of a particular pixel and if there are odd number of white pixels you have found a corner. Or use a 4-neighborhood and test for even number of white pixels.
