Four dimensional matrix discrete cosine transformation-based remote education video compression technical research
Remote education seriously is a kind of newly-developed teaching technique, the technique development can provide stronger impetus for education development, and in the technique implementation process, it faces slow video transmission and big material consumption in documents saving such problems, if it can look for a kind of effective algorithm targeted video compression coding, then it can alleviate the problem to some extent. The paper researches on video image sequence features, uses four dimensional matrix discrete cosine transformation algorithm to make compression code on video image files, in the research process, the paper firstly states four dimensional matrix definition and computing ways, and then discusses four dimensional matrix cosine transformation mathematical algorithm and video coding process involved compression algorithm, and finally uses paper stated video code compression algorithm to get evaluation table data in DSP. Data shows that four dimensional matrix discrete cosine transformation-based video compression code algorithm has obvious superiorities by comparing with other algorithms, which provides theoretical algorithm for video coding and provides technical support for remote education lots of implementation.
