The basic algorithm I would use to start with goes something like this. As the code gets more mature I would look to refine and optimize it.

Loop through each pixel in the image:
    if the pixel's calculated luminance is more than a set constant:
         record pixel's location
         if none of the eight neighboring pixels are recorded:
             increment the star count

Note that I haven't looked at this algorithm for design flaws or potential problems, but its simplicity makes it good as a starting point.
