In this paper we propose an edge-directed error concealment (EDEC) algorithm, to recover lost slices in video sequences encoded by flexible macroblock ordering. First, the strong edges in a corrupted frame are estimated based on the edges in the neighboring frames and the received area of the current frame. Next, the lost regions along these estimated edges are recovered using both spatial and temporal...
We present a new error concealment algorithm for spatially scalable video coding with frame loss in the enhancement layer, based on the technique of hallucination. For a lost enhancement layer frame, the error concealment is done as hallucinating its base layer frame, using the database trained from previously decoded frames nearby to the lost one. Simulation results show that the proposed method...
We propose a new error concealment method based on hallucination for Scalable Video Coding with spatial scalability. In this method, parts of the frames which lose the enhancement layer are up-sampled from base layer and ldquohallucinatedrdquo as concealment frames. The database for hallucination is generated from the high-resolution and low-resolution frame-pairs near the lost frames in the video...
