MESH CODING OPTIMIZATION OF TELEVISION IMAGES

Abstract

This paper considers the search for the optimal combination of connectivity methods of coding and mesh geometry of three-dimensional television facilities. Proposed to use for encoding Edgebreaker topology algorithm in which the connection is described by labels and the labels are presented in arithmetic lossless entropy code. Coding geometry invited to perform with the help of parallel processing, and the vertices of the triangles codes in the residual class followed by recoding the modified Fibonacci series. A formula for calculating the bit rate for the combined mesh coding algorithm is presented. It is shown that the rate depends on the bit of code labels and the bit of code vertices. The gain in bit rate when using the proposed method combined with an increase in the number of triangles in the mesh model is 70%. When encoding geometry parameter of average bit rate can be reduced up 8 bits/triangles.
