Abstract
A system and a method are disclosed for encoding and decoding a video frame using spatial prediction. The video frame is separated into a plurality of image blocks, and a plurality of spatial predictors is created for an image block using methods well-known in the art. The set of predictors is reduced to a set containing fewer spatial predictors before continuing the coding process for the block. The reduction of spatial predictors involves comparing a plurality of spatial predictors in a predetermined sequence and grouping or processing a subset of the spatial predictors to a set of representative spatial predictors.
