C# Class Accord.Imaging.Filters.Grayscale.CommonAlgorithms

Set of predefined common grayscaling algorithms, which have already initialized grayscaling coefficients.

Public Properties

Grayscale image using BT709 algorithm.

The instance uses BT709 algorithm to convert color image to grayscale. The conversion coefficients are: Red: 0.2125; Green: 0.7154; Blue: 0.0721.

Sample usage:

// apply the filter Bitmap grayImage = Grayscale.CommonAlgorithms.BT709.Apply( image );

public static Grayscale,Accord.Imaging.Filters BT709
return	Grayscale

Grayscale image using R-Y algorithm.

The instance uses R-Y algorithm to convert color image to grayscale. The conversion coefficients are: Red: 0.5; Green: 0.419; Blue: 0.081.

Sample usage:

// apply the filter Bitmap grayImage = Grayscale.CommonAlgorithms.RMY.Apply( image );

public static Grayscale,Accord.Imaging.Filters RMY
return	Grayscale

Grayscale image using Y algorithm.

The instance uses Y algorithm to convert color image to grayscale. The conversion coefficients are: Red: 0.299; Green: 0.587; Blue: 0.114.

Sample usage:

// apply the filter Bitmap grayImage = Grayscale.CommonAlgorithms.Y.Apply( image );

public static Grayscale,Accord.Imaging.Filters Y
return	Grayscale
