Adaptive spatial-temporal error concealment algorithm for AVS-M
基于AVS-M标准的自适应时-空域差错掩盖算法

To reduce the influence on video decoding quality induced by transmition error, This paper analyzes several classical error concealment methods and evaluates them on AVS-M. Based on the test result, an adaptive spatial-temporal error concealment (ASTEC) algorithm is proposed. According to the boundary matching degree of switch between spatial/temporal concealment methods adaptively. Simulation results show that, compared with the original spatial and temporal method, the proposed algorithum achieves better performance, especially on the quality of reconstructed image.
