Texture aware image error concealment

Abstract

Error concealment is an error control technique capable of mitigating the error effects on multimedia using only the correctly received data. We introduce an efficient and highly scalable concealment algorithm for textured colour images. The lost area is restored by texture extrapolation from the surrounding regions logically associated on the superpixel level. With the proposed method also edges located in the lost area are retained. We validate results of the experiments against state of the art methods and demonstrate that our proposed algorithm performs much faster.

Fast‐efficient shape error concealment technique based on block classification

“…There are two general approaches to overcome shape error: spatial processing and temporal processing [3–17]. In this paper, we study spatial interpolation to recover missing intra‐shape blocks.…”
