Abstract :
In this paper we formulate an optimized temporal error concealment approach for H.264 based on the study of the performance of several temporal concealment features that apply to the different steps of the proposed method. Specifically we study how the concealment performance is affected by matching error measures, motion vector candidates and estimation enhancements. We show that the resulting formulated method performs significantly better than other state of the art methods. The proposed approach can prove very valuable to the mitigation of errors typically encountered with video transmission over wireless networks.
