MatchHistogramCommand Class

Summary

Transforms an image so that its histogram matches another images's histogram.

Syntax
C#
VB
C++
public class MatchHistogramCommand : RasterCommand 
Public Class MatchHistogramCommand 
   Inherits RasterCommand 
public: 
   ref class MatchHistogramCommand : RasterCommand 

Remarks

This command supports 8-bit grayscale and 24-bit color images only.

If the image to be transformed is 8-bit grayscale then the reference image must be 8-bit grayscale also.

If the image to be transformed is 24-bit color then the reference image can be 8-bit grayscale or 24-bit color.

Use the Run method to apply the matching on the image.

Example
C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Effects; 
 
public void MatchHistogramCommandExample() 
{ 
   //Load the two images 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
   RasterImage RefBitmap = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon.jpg")); 
   RasterImage Bitmap = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "cannon_HistogramMatchingSample.jpg")); 
 
   //Prepare the command 
   MatchHistogramCommand command = new MatchHistogramCommand(RefBitmap); 
 
   //Apply 
   command.Run(Bitmap); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
}
