you need to really model what is going on at the edge boundary. For an individual pixel, how much of the contribution is from the background, and how much is from the object? Pixels values are the result of a smoothing operation over each pixels field of view (which is actually probably a little bit bigger than the image dimensions suggest). When you zoom into an image its clear that the edges of objects can affect pixel intensities a few pixels away (blur). So you have to reverse that which can be tricky. Image people like Matlab so thats where the premade solution will be found
