Error concealment using motion field interpolation [PDF]

, 1998
In the context of block-based video coding, two error concealment algorithms are presented. The first algorithm is based on bilinear motion field interpolation (BMFI). For each pel in a damaged block, the algorithm recovers a motion vector using bilinear
