Looking for Image Compresssion Demonstration Applet

  1. Sep 18, 2012 #1
    Hello All,

    I hope I'm in the correct category, please let me know if I'm not. I'm looking for an applet on the web that I came across a few years ago. It demonstrated the basics of image compression by letting the user select from various transforms (DCT, some form of wavelet, a couple I can't remember) and clip off a portion of the transform 'image'. It would then show the reconstructed image to demonstrate how the loss of information affected the output.

    I know there are a few that are similar to this, but that was the only one that I've come across that allowed a choice amongst different types of transforms. One of them even involved some sort of 'random' decomposition.

    For the life of me I can't find it so I was wondering if anyone knows which one I'm talking about (or even "I think I remember that...") I'd really appreciate any info.
