OPTIMIZATION OF ALGORITHMS COMPRESSION OF THE DATA FOR THE STANDARDS MPEG-2, MPEG-4 AND MODELS 3-D THE GRAPHICS
The results of researches of the authors are reported in the field of optimization algorithms compression given for the standards MPEG-2, MPEG-4 and models 3-D graphics.
For the standards MPEG-2 essential acceleration of coding in comparison with model TM-5 is achieved at the expense of optimization integer discrete cosine transformation (DCT), application hierarchical scheme of an estimation of movement (motion estimation) and improvement of a way of management by the vbv-buffer. For the next versions of the standard MPEG-4 the results coding on the basis of Wavelet-transformations are given having conclusive advantages above usual DCT. The new approach for the decision problems of compression the 3-D graphics models is shown as traditional ways compression in this case can not be used.
The report is illustrated by the data of the comparative analysis, examples coded / restored as separate test images and their sequences.
