Study on the adaptive error concealment technique for mobile video

In order to achieve the effect of covering up the image error and improve the visual effect of the image, this paper analyzes error concealment technique in three aspects of the spatial, time and frequency domain, and then proposes an adaptive time-domain error concealment algorithm. The results show that: the effect of applying the adaptive method proposed in this article is better than that of the linear interpolation, the block effect is evidently eliminated. Better than the motion vector compensation, part of the local texture information is better recoveried. The value of PSNR of applying the proposed adaptive method is averagely higher than any single method.
