The BCC RGB Edges filter finds edges in each RGB channel independently,
creates a new RGB image from these edges, and applies the new image to the
source using the chosen Apply Mode and Apply Mix.
The results obtained with the edge filters vary depending on the media to which
the filter is applied and the exact settings used. Because they create edge
effects by emphasizing differences between adjacent pixels, edge filters are
very sensitive to parameter adjustments. Often a small change in a parameter
setting can dramatically affect the result.
The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
