I don't see the usefulness of the code. It is too simple.

I don't see how this uses color information at all. It seems as though it's just using the Y signal to do edge detection, which is really just a grayscale of the image, right?

- Does not use colour information for edge detection.
- Bad programming style (e.g. takes filename of image instead of image etc.)
