    TICO equivalent compression algorithm

    Dear Compressors,

    I am looking for an open source equivalent to TICO, a new commercial lossless compression technique
    for images.

    http://www.intopix.com/news/index/re...n#.VM4y_C7lyeI

    "TICO assures visual quality using a 2:1 to 4:1 compression ratio, but keeps power and bandwidth at a reasonable budget.
    On top of this, its selectable latency down to as little as 1 pixel line ensures absolute real-time and instant operation. "

    Unfortunately, I don't have any more details on TICO, except that it is lossless, supports 2:1 and 4:1 compression ratio,
    and has low latency.

    Given this information, can anyone recommend an open lossless algorithm that would meet these criteria?

    Thanks so much,
    Aaron

    (Low latency is a key feature here)

    There is also an emerging standard for this type of compression, from SMPTE:

    https://kws.smpte.org/kws/public/pro...?project_id=15

    This description gives a bit more information on what is needed in this type of compression.

    Thanks!

    Lossless algorithm that lets you pick compression ratio of 2:1 or 4:1?
    Marketing nonsense. It doesn't mean the algorithm is junk, but the smell is bad.

    Sorry, my bad. 2:1 to 4:1 So, it looks like it supports a range of compression ratios.

    Actually, TICO is lossy, even though it is "visually lossless", which is not quite the same. Its target was a 2:1 compression ratio. There was a whole test procedure developed around this visually lossless stuff, which is now ISO/IEC 29170-2.

    As a side remark, VESA jointly with JPEG started a new iniitative for low-latency/low-complexity coding, even though the target is now visually lossless at 4:1 (not 2:1), so it is getting harder. The goal is here of course that this should/will be used in UHD screens as display link since the bandwidth of the connection (even with modern cables) is too limited to the resolution. Even though you don't see the compression here, the overall product reminds me a little bit of what happens with analog signals: If the bandwidth isn't sufficient, the quality goes down.

    If anyone is interested joining the initiative, you can subscribe to our mailing list at

    This requires a short review, so please feel prepared to ask for your motivation and background. It's only that we don't want spammers on the list.

    Greetings,

    PS: Yes, it's currently coined JPEG-XS (extra speed), though it's probably sort of engineers' humor; guess we had to fill the gap between XR and XT.
