I wrote a lot of image (and not only image) processing algorithms. Most of them were for military proposes. Almost all of them are not secret, so why not to use war technologies for peace manners? Sitting one of those long evenings, I wrote a simple application, that seeks for similar (not by name of cause) images in your hard disk and make you able to delete them. I will not explain the search algorithm here, but post the application for free download. Try it, use it and tell me what you think about.
Following examples of images found by this application.
The algorithm used is not optimized for such operations, thus it takes about one minute to find first duplicate in directory of 200 images 2048X1536. Final result comes after about three minutes.
Maybe in the future, I'll optimize those algorithms for everyday use. It depends only on you, my readers, wish to tell me about how the application is.
To use: Run application, browser for start directory or drop directory from windows explorer and hit Search. After results will arrive, select original image from the left and duplicate from the bottom. If you wish to delete one or both of them, hit red cross under each one of those images. Happy use. Don't forget to tell me how it was.
