Class Raise_Contrast_Fast

Ch03_Point_Operations.Raise_Contrast_Fast

All Implemented Interfaces:

PlugInFilter, JavaDocHelp

public class Raise_Contrast_Fast
extends Object
implements PlugInFilter, JavaDocHelp

This ImageJ plugin does the same as the Raise_Contrast plugin but uses the one-dimensional pixel array to read and writes pixel values without calling any intermediate access methods, which is obviously more efficient. See Sec. 3.1.1 of [1] for additional details.
