C# Class AForge.Imaging.Filters.AdditiveNoise

Additive noise filter.

The filter adds random value to each pixel of the source image. The distribution of random values can be specified by random generator.

The filter accepts 8 bpp grayscale images and 24 bpp color images for processing.

Sample usage:

 // create random generator IRandomNumberGenerator generator = new UniformGenerator( new Range( -50, 50 ) ); // create filter AdditiveNoise filter = new AdditiveNoise( generator ); // apply the filter filter.ApplyInPlace( image );
