Class YCbCrFiltering

java.lang.Object

Catalano.Imaging.Concurrent.Filters.YCbCrFiltering

All Implemented Interfaces:

IApplyInPlace

public class YCbCrFiltering
extends java.lang.Object
implements IApplyInPlace

Color filtering in YCbCr color space. The filter operates in YCbCr color space and filters pixels, which color is inside/outside of the specified YCbCr range - it keeps pixels with colors inside/outside of the specified range and fills the rest with FillColor specified color.
