A little demo to showcase the ERODE and DILATE filters in action.

• click - apply currently active filter
• SPACE - toggle between ERODE (grow dark areas) and DILATE (grow light areas)
• L / l - re-load image

These filters can come in handy for computer vision tasks (e.g. noise removal or as part of an image/feature segmentation process). In general there are other possible kernel shapes for this type of filter, though the diamond shaped one (as used here) performs fastest.
