    Question QuikCAT Miliki Super Compressor

    I found a compressor which called as Shrink from LAFE Technologies and it is advertised as "compresses documents and images up to 10x more than ZIP software". In their site ( there are some benchmark results. Here is one of them:

    After guessing something about it, I decided to test it. But, I didn't find any trial version in their site for testing it. Then I searched from google and found some (probably) old version of it. It was QuikCAT Miliki Super Compressor. Here is the test results for Miliki vs PAQ8o8

    Summary for Miliki
    Sum of Compressed File Size: 10,885,757 bytes
    Single Archive Size:         10,885,514 bytes (it's clear there is no "Solid Mode")
    I think, all of you already guessed what's going on. It's clear that they are using a lossy compression method for images (maybe with precomp like deflate recompression). For proving this, here is the decompressed files from Miliki (only listed which has different CRC32 with original file):
    File          Original Size   Decompressed Size
    A10.jpg             842,468             255,646
    FlashMX.pdf       4,526,946           2,929,632
    rafale.bmp        4,149,414           4,149,414
    In Miliki Settings, it's obvious that there is a lossy image compression algorithm. Because, there is a slider for selecting image degradation. According to degradation of the image which in Settings dialog, someone is able to easily guess Miliki's algorithm: wavelet (JPEG like DCT algorithms degrades images into mosaic looking while JPEG 2000 like wavelet algorithms degrades images into muddy looking). Note that, all of test were made with "No degradation" mode. But, it seems in even "No degradation", there is still degradation. So, I decided to test it in pixel-to-pixel. I extracted differences between original and decompressed version of rafale.bmp in Photoshop. Even before magnification differences, I was able to easily see the differences. After magnification, I saw that differences were in everywhere!

    Here is the download links for trial version: (Trial for 30 days) (Trial for 14 days)

    I had tested "Trial for 14 days" version. Seems both versions are identical. Installing on Vista x64 SP1 was failed. So, I installed it on WinXP SP2 under VMWare and tested.

    It's known that Miliki is lossy.
