Single color processing with the Imaging Whiteboard

The Imaging Whiteboard Users Guide has a screen shot that shows how the threshold control can be used to separate the color components of an image.

This screen shot shows how the FFT filter can be applied to the green component of the checkerboard test pattern.

Note that the FFT result is also shown as green. (Click image for a better view)
