    UCI Image Compression

    http://wex.cn/dwing/mycomp.htm

    UCI is one kind based on H.264 the intra frame compression algorithm and the data stream form frozen picture seal form. Moreover the image wide high some limits, is not supported characteristics and so on alpha transparent channel, with frozen picture compression algorithms and so on JPEG, JPEG2000, HD-Photo compares has the higher efficiency of compression. Arranged decodes the tool and the decoding middleware initial edition already developed completes, the tool supported BMP and the UCI form interconversion temporarily, used x264 to take the code essence, FFmpeg takes the decoding essence and the partial imagery processing.

    in short its a lossy compression ( i could not make run.. i always got error= -52)

    You need x264.exe on http://x264.nl to make ucienc.exe work.
    I've just tried it, which shows much better performance than JPEG2000 at high compression rate.
    And it tends to reserve the informations that sesitive to humans' nake eye. Actually I've been shocked how good the H.264 intra-frame coding algorithm is.
    Now the author of UCI had moved his homepage to http://tieba.baidu.com/f?kw=dwing, and you can find the newest version of UCI in the top-most post.
    The only problem is the texts are almost totally in Chinese. Maybe someone could ask the author to provide an English version.

    Good work. Consider talking with khavish on https://encode.su/threads/2811-Psych...n-image-codecs to include your codecs there.
