Wow, excellent paper! Looks like a lot of research went into it. I read most of it, but don't really understand the math formulas as they're beyond my understanding.Hate to reply to an old thread, but I put your clever little test image to good use.
And I can now answer the question of how HighPass sharpening differs from USM. They both start off the same way: by subtracting a Gaussian blurred version from the original. But the USM adds the difference directly back to the original, whereas the High Pass sharpen has to use a blend mode to do the workand the formulas are not the same.
