Temporal Error Concealment Algorithm Using Adaptive Multi-Side Boundary Matching Principle


Seung-Soo Jeong, Chae-Bong Sohn


Vol. 8  No. 12  pp. 184-189


The environment of transmission via a wireless network is not always error-free. The loss of data or impairment caused by errors degrades the quality of image. The error concealment is the method that finds the best substitute information from the previous reference image with the boundary information around lost block. Therefore, This paper proposes an Adaptive Multi-Side Boundary Matching principle (AMSBM). AMSBM has two steps. First, the boundary matching degree examination on the boundary information is conducted. Second, AMSBM decides which data is the most reliable and conceals the lost block with the most reliable data. Experimental results show an improved performance of 0.36 dB on average compared to the previous method.
