Abstract For the lack of BMA, the motion objectsthe edge profile of objects and details hidden is not beautiful, an improvement of BMA algorithm and a residual error recovery interframe error hiding algorithm were put forward on the basis of the comprehensive effect of hidden and algorithm complexity. The following four aspects were improved: 1) Expand and modify vector set of candidate motion; 2) Modify restriction of BMA algorithm; 3) Selectively introduce Linear interpolation to get estimated residual value of damaged macro block; 4) Selectively introduce residual recovery. Validated by simulation experiment, the experiment indicates that the proposed algorithm is obviously improved the processing ability to the motion objectsthe edge profile of objects and details hidden. Peak signal to noise ratio have significantly increased and the algorithm complexity is low. This algorithm is suitable for real-time applications.
