Abstract

The performance of conventional error concealment (EC) is significantly affected by the method of selecting candidate motion vectors (MVs). In order to obtain more robust EC results, this letter proposes a new and efficient way to choose candidate MVs. The proposed approach systematically utilizes available neighboring MVs by exploiting a well-known spatiotemporal correlation of block MVs. Through extensive simulations with H.263, this letter demonstrates that the proposed candidate MVs provide superior concealed video quality in comparison to the best results of other existing techniques.
