    • Informal codecs comparison

    As one can see on the diagrams above different codecs show significantly different results for different sequences. That happens because all the represented sequences have different character (motion, noise e.t.c.). This fact allows to define which codecs do well with any kind of video sequences and which provide good results only for some class of sequences. However it would be interesting to find out general characteristics of each codec on the whole testing set.

    We decided that averaging resulting values for all the sequences won't be correct and suggested an informal estimation where every codec is given some score depending on the results of its measurement.

    Informal comparison rules

    • If some codec is stably better than all the others in more than one point it is given score 3 regardless of other results.
    • If some codec is worse than all the others in more than one point it is given score 1.
    • Otherwise score 2 is assigned.
    • Y-PSNR, U-PSNR, V-PSNR and Y-difference parameters are estimated using this method.

    Common conclusion

    • Standard was adopted not long ago - in the end of 2003. At the same time H.264 algorithm is significantly more complex, than previous standards and requires more tuning time. As a result many codecs, used in this comparison, are works in progress, that require much time before achieving product quality
    • In the test start we planned to compare different codec compatibility in between and standard conformance. But simple tests shown that currently it is too early to test codec compatibility.
    • Codecs that participated in our testing were optimized for maximum performance on current day computers, and do not employ all H264 format possibilities. Afterward with computers performance growth it would be possible to show better results even without data format changes. We could suggest following analogy: current H264 codecs are approximately on a level of DivX 2.0 - so they are not ready for mass distribution. But if quality increase in next versions would be similar to increase from DivX 3 to DivX 5 than format advantages would be noticeable.

    Public MSU video filters
    Here are available VirtualDub and AviSynth filters. For a given type of digital video filtration we typically develop a family of different algorithms and implementations. Generally there are also versions optimized for PC and hardware implementations (ASIC/FPGA/DSP). These optimized versions can be licensed to companies. Please contact us for details via video(at)graphics.cs.msu_ru.     		Filters for companies
    We are working with Intel, Samsung, RealNetworks and other companies on adapting our filters other video processing algorithms for specific video streams, applications and hardware like TV-sets, graphics cards, etc. Some of such projects are non-exclusive. Also we have internal researches. Please let us know via video(at)graphics.cs.msu_ru if you are interested in acquiring a license for such filters or making a custom R&D project on video processing, compression, computer vision.
