ABSTRACT
Compressed video sequences are very sensitive to channel
disturbances when they are transmitted through an unreli-
able environment such as a wireless channel. The trans-
mission errors not only corrupt the current decoded frame,
but also propagate to the succeeding frames. Many error
concealment methods have been proposed to recover the er-
rors by exploiting temporal and spatial correlation. In this
paper, we develop a multi-frame boundary matching algo-
rithm (MF-BMA), which utilizes the boundary smoothness
property not only in the decoded frame but also in the suc-
ceeding frames. The experimental results demonstrate that
the proposed algorithm can provide better performance, es-
