The coding gain of the H.264/AVC video encoder mainly comes from the new incorporated prediction tools. However, their enormous computation and ultrahigh memory bandwidth are the penalties. In this paper we present an approach supporting efficient data reuse process to avoid unnecessary memory accesses and redundant motion estimation computations combined(More)
A merging procedure joining search origin, search pattern and new variable block size motion estimation for H.264/AVC is proposed in this paper. Those approaches yield good tradeoffs between motion estimation distortion and number of computations since they invest and exploit the center-biased characteristics of the real world video sequences: A reliable(More)
The coding gains of the H.264/AVC video encoder, come from the improvement of the prediction method for intra and inter prediction in goal to achieve best image quality. However, their enormous computation, high complexity and the dissipated power are the main penalties. The approach proposed in this paper invests and exploits the best hardware solution for(More)
The high performance of H.264/AVC video encoder is accompanied with a wide computation complexity especially for high definition (HD) video sequences. One of the major H.264/AVC features to be optimized is the mode decision for both inter and intra prediction. Thus, based on high correlation observed between selected inter prediction mode and intra mode(More)
Motion estimation and compensation techniques are widely used for video coding applications but the real-time motion estimation is not easily achieved due to its enormous computations. Therefore, it would be greatly beneficial to optimize as much as possible the motion estimation bloc which is considered to be the most important in terms of computational(More)
