Intra-frame prediction exploits spatial redundancy, i.e. correlation among pixels within one frame, by calculating prediction values through extrapolation from already coded pixels for effective delta coding. It is one of the two classes of predictive coding methods in video coding.
Intra-frame prediction relies on spatial coherence, i.e., the similarity among pixels within a single frame, by employing extrapolation from already coded pixels to achieve efficient delta encoding. It is part of the broader category of predictive coding techniques used in video compression.
