An error concealment algorithm based on motion field interpolation is prese
nted. For each pixel in a damaged block, thr algorithm recovers a motion ve
ctor using bilinear interpolation of neighbouring motion vectors. This vect
or is then used to conceal the damaged pixel. Overlapped motion compensatio
n is used to combine this algorithm with a boundary matching error concealm
ent algorithm. Simulation results demonstrate thr superior performance of t
he proposed algorithms.
