A SHAPE ERROR CONCEALMENT TECHNIQUE FOR ROBUST MPEG-4 SYSTEM

Abstract

This paper presents a fast-efficient error concealment method for recovering the shape information. The proposed technique consists of the block classification, the edge direction interpolation and the filtering interpolation. The missing block with the logic criterion is classified to four types that are transparent, opaque, edge and isolated blocks. Most of the computations cost on the edge block and the isolated block to obtain better cost-performance tradeoffs. For the edge-block recovery, the edge slope is computed by referring the near available block, and then the missing shape is interpolated along the edge direction. We deal with the isolated block using the cascaded filter to approximate the real shape. The experimental results show that the proposed method can achieve better cost-performance to restore the shape information compared to the other competing algorithms in both of the numerical parameters and the shape images. The processing speed is faster about 2~3 times to the well-known methods. The adaptive algorithm employed the low computational load overhead to make it applicable to a real-time MPEG-4 coding system.
