advances in videophone place higher quality on human facial images. To tackle this issue
a new spatial error concealment algorithm based on the facial features (FFSEC)is proposed in this paper. The algorithm is constituted by three steps. First
the lost blocks are classified by the edge detection technique so as to finish the preliminary error concealment. Second
the facial area is extracted by the facial partition technique. Finally
an interpolation is implemented according to the relative position and specific feature of the five organs
where the position of eyes is obtained by the pattern recognition technique at first. JM11 model of H.264 standard is used to evaluate this FFSEC algorithm. Simulation results showed that compared with the existing adaptive spatial error concealment based on face features (BFASEC)algorithm
when the packet dropping probability is too large
the FFSEC algorithm achieved better visual quality
