Abstract
A block intra prediction direction detection algorithm comprises acts of dividing a block, finding directions from edge assent rules, determining a main edge of the block, selecting prediction modes from the main edge, choosing base prediction modes and using all unique selected and base prediction modes in intra prediction. The algorithms comprise a 4×4 block intra prediction direction detection algorithm, a 16×16 luminance block intra prediction direction detection algorithm and an 8×8 chrominance block intra prediction direction detection algorithm.
