C# 클래스 AForge.Imaging.ExhaustiveTemplateMatching

Exhaustive template matching.

The class implements exhaustive template matching algorithm, which performs complete scan of source image, comparing each pixel with corresponding pixel of template.

The class processes only grayscale 8 bpp and color 24 bpp images.

Sample usage:

 // create template matching algorithm's instance ExhaustiveTemplateMatching tm = new ExhaustiveTemplateMatching( 0.9f ); // find all matchings with specified above similarity TemplateMatch[] matchings = tm.ProcessImage( sourceImage, templateImage ); // highlight found matchings BitmapData data = sourceImage.LockBits( new Rectangle( 0, 0, sourceImage.Width, sourceImage.Height ), ImageLockMode.ReadWrite, sourceImage.PixelFormat ); foreach ( TemplateMatch m in matchings ) { Drawing.Rectangle( data, m.Rectangle, Color.White ); // do something else with matching } sourceImage.UnlockBits( data );

The class also can be used to get similarity level between two image of the same size, which can be useful to get information about how different/similar are images:

 // create template matching algorithm's instance // use zero similarity to make sure algorithm will provide anything ExhaustiveTemplateMatching tm = new ExhaustiveTemplateMatching( 0 ); // compare two images TemplateMatch[] matchings = tm.ProcessImage( image1, image2 ); // check similarity level if ( matchings[0].Similarity > 0.95f ) { // do something with quite similar images }
