PROJECT AIM

    AIM OF PROJECT "Everything about the data compression" is creation and provision of

maximally full,

maximally clear,

maximally useful

    data compression resource for everyone.

    The project is non-commercial and is supported by the Computer Graphics and Multimedia Laboratory on the computing mathematics and cybernetics department of MSU (Moscow State University).

Priority directions

Server is filled with Russian materials first of all, and materials of Russian authors. Simply because such servers are too little. Moreover, such articles are scattered in many magazines, so it's difficult to get them even if you know where and what to look for.

We specially collect materials with serious scientific directivity, which are useful for creating powerful compressors and codecs of state-of-the-art level. Alas! such materials are usually written in English even in those cases when the authors are Russian-speaking.

We specially collect and write materials popularly explaining main points of various compression methods functioning.
