Abstract
In MPEG-4, the boundary macro-blocks of reference video objects are padded by replicating the boundary samples towards the exterior. The authors propose the introduction of a linear extrapolation based pre-padding step to minimise prediction errors. Experimental results indicate that gains of up to 7% can be achieved for boundary macro-block coding by this proposed technique
