Parameters

width: The width of the local histogram equalizer rectangle in pixels. The width should be more than zero.
height: The height of the local histogram equalizer rectangle in pixels. The height should be more than zero.
widthExtension: The extension of the width of the local histogram equalizer rectangle, in pixels.
heightExtension: The extension of the height of the local histogram equalizer rectangle, in pixels.
smooth: Size of the area to be used when smoothing the edges between localized blocks. Possible values are between 0 and 7, but if Height is less than or equal to 7 then the maximum value for this item is Height - 1. If Smooth = 0 the edges will not be smoothed.
type: Flag that indicates which color space to equalize.
