One of the new features in the H.264/AVC encoder is the use of Lagrangian Rate-Distortion Optimization (RDO) method during mode decision at the macroblock level. The RDO technique has been employed in H.264/AVC for intra prediction mode selection to achieve better coding efficiency. But the computation complexity of mode decision algorithm is extremely high. To reduce the complexity of mode decision, we propose an efficient and fast 4x4 intra prediction mode selection scheme. The proposeddoi:10.1109/icalip.2008.4590056 fatcat:6njppocskbcp7nkm4cg37tiqsi
