    Hi Everyone,

    Just wondering if anyone knew of a way to compare images and getting a
    nearest matching image out of a collection of images of diffrent
    sizes, colors, etc. Ideally want to compare the general shape of the
    main features in the image, would be nice if it also compared the
    average color value. I've done a bit of hunting on google and only
    really come up with solutions that match pictures based on their file
    hash value or solutions that are pure math without some general guides
    on implementation in C#.

    Thanks in advance,
    Max

  2. I think you want to look for something closer to face recognition or motion
    detection algorithms, or a classifier type of neural net.

    Hi Peter,

    Thanks for your feedback; to be honest it's to make a simple piece of
    software that generates those mosaic pictures, just a simple personal
    project. Can you provide some reference material explaining some of
    the mentioned suggestions? I have looked over those topics previously,
    but had difficulty finding a way to use them.

    Thanks,
    Max
