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 interpolation of neighbouring motion vectors. This vector is then used to conceal the damaged pel. A(More)
A fast block matching motion estimation algorithm is presented. The algorithm is based on a generic unconstrained optimisation technique called simplex minimisation (SM). In order to apply this method to the constrained minimisation problem of block matching motion estimation, a suitable initialisation procedure, termination criterion, and constraints on(More)
