The attached project uses LEADTOOLS Image Processing functions to illustrate how to find the differences between two similar images. The function will determine the bounding area where all differences occur, then crop the image containing the differences so all other image data is excluded.

This is typically used to find small changes in an image so that most of the original image is removed and only the changed area remains.

C# Console Project was created using Visual Studio 2013 and using LEADTOOLS .NET API Version 19

Updated the example for Visual Studio 2017 using the LEADTOOLS .NET API Version 20. There are sample images included with the project in the "Files" directory

To test the project, simply run the following from command prompt:

Code:


C:\LEADTOOLS 20\Bin\Dotnet4\Win32> Deconstruct.exe <path-to-original-image> <path-to-changed-image>

Or configure the debug settings in Visual Studio to have the above arguments when running:

Right-click the project and choose "Properties"
Under the "Debugging" or "Debug" section, there is a box for "Command Arguments"
