[C#] Finding an image in another image(using AForge)

[alien]

This is a simple example using C# and AForge of how you can detect if ImageA is found in ImageB.

AForge is a C# framework designed for developers and researchers in the fields of Computer Vision and Artificial Intelligence - image processing, neural networks, genetic algorithms, machine learning, robotics, etc.

You can add it to you're project as a NuGet package or from their website

AForge.NET :: Computer Vision, Artificial Intelligence, Robotics

The code is very straight forward:

- you load to images(source and template)

- you create a ExhaustiveTemplateMatching from AForge

- you store the found matches in a TemplateMatch

             System.Drawing.Bitmap sourceImage = (Bitmap)Bitmap.FromFile(SourceInput.Text);
            System.Drawing.Bitmap template = (Bitmap)Bitmap.FromFile(TempateInput.Text);
            // create template matching algorithm's instance
            // (set similarity threshold to 92.5%)

            ExhaustiveTemplateMatching tm = new ExhaustiveTemplateMatching(0.921f);
            // find all matchings with specified above similarity

            TemplateMatch[] matchings = tm.ProcessImage(sourceImage, template);
            // highlight found matchings

            foreach (TemplateMatch m in matchings)
                MessageBox.Show(m.Rectangle.Location.ToString());
