VTK Examples

Those two simple plugins perform one-sided 3x3 median filtering:

	Median Light: Performs median filtering only on light pixels, that is, a pixel is modified only if its intensity is more then a median intensity value in its neighborhood.
	Median Dark: Performs median filtering only on dark pixels, that is, a pixel is modified only if its intensity is less then a median intensity value in its neighborhood.

Examples

	Test image with noise.
	Test image after applying "Median Dark" filter - only dark spots are removed.
	Above image after applying "Median Light" filter - white spots are removed.
