C# Class AForge.Imaging.Filters.ExtractNormalizedRGBChannel

Extract normalized RGB channel from color image.

Extracts specified normalized RGB channel of color image and returns it as grayscale image.

Normalized RGB color space is defined as: r = R / (R + G + B ), g = G / (R + G + B ), b = B / (R + G + B ), where R, G and B are components of RGB color space and r, g and b are components of normalized RGB color space.

The filter accepts 24, 32, 48 and 64 bpp color images and produces 8 (if source is 24 or 32 bpp image) or 16 (if source is 48 or 64 bpp image) bpp grayscale image.

Sample usage:

 // create filter ExtractNormalizedRGBChannel filter = new ExtractNormalizedRGBChannel( RGB.G ); // apply the filter Bitmap channelImage = filter.Apply( image );
