Intra-mixture Prediction Mode and Enhanced Most Probable Mode Estimation for Intra Coding in H.264/AVC
TL;DR: IMP mode supports more flexibility in intra prediction by mixing 4x4 blocks and 8x8 blocks in one macroblock, while the enhanced MPM estimation extends the number of referenced neighboring blocks and efficiently uses their prediction modes depending on their positions.
