摘要：
Low-complexity error concealment techniques for missing macroblock (MB) recovery in mobile video delivery based on the boundary matching principle is extensively studied and evaluated in this work. We first examine the boundary matching algorithm (BMA) and the outer boundary matching algorithm (OBMA) due to their excellent trade-off in complexity and visual quality. Their good performance is explained, and additional experiments are given to identify their strengths and weaknesses. Then, two more extensions of OBMA are presented. One is obtained by extending the search pattern for performance improvement at the cost of additional complexity. The other is based on the use of multiple overlapped outer boundary layers.
