H.264 or MPEG-4 AVC (Advanced Video Coding) is the new world-wide accepted international Standard for video coding, approved by ITU-T and ISO. New Tools have been added to improve the coding efficiency allowing a save up above of 50%, when is compared with previous standards (H.263, MPEG-2 y MPEG-4). From April 2007 there is a new set of profiles known as “all-Intra”. They were born as a sub-se...

Next generations of image and video coding methods should of course be efficient in terms of compression, but also propose advanced functionalities. Among these functionalities such as scalability, lossy and lossless coding, data protection, Rate Distortion Optimization (RDO) and Rate Control (RC) are key issues. RDO aims at optimizing compression performances, while RC mechanism enables to exa...

Received April 9, 1963 We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate @DO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of Rscherichia coli 0111-B& and the enzymatic synthesis of CMP-RDO (Ghalambor and Heath, 1963). This report presents evidence for the chemical synthesis of KDO and its enzymatic cleavage (RDO-ald...

The state-of-the-art video coding standard H.264/AVC achieves significant coding performance by adopting variable block sizes for motion estimation (ME) and mode decision. However, this technique brings out high computational complexity since the optimal mode is determined by exhaustively performing rate-distortion optimization (RDO) on each coding mode with different block sizes. In this paper...

The technique isolated regions, which is based on constraining inter and in-picture prediction jointly, was adopted into the emerging video coding standard H.264 (also know as MPEG-4 part 10 or AVC), as a tool to provide gradual random access and error resilience among other things. This paper addresses the error resiliency performance of isolated regions in the aspect of error-robust inter/int...

H.264/AVC, the newest international video coding standard achieves higher compression efficiency as compared to all other existing coding standard such as MPEG-4 and H.263. However this efficiency comes with a dramatic increase in computational complexity due to several advanced techniques, such as inter mode and intra mode prediction with variable size motion compensation. It adopts rate disto...

A fast H.264 Intra prediction mode selection scheme is proposed in this work. The objective is to reduce the encoder complexity without significant rate-distortion performance degradation. The proposed method uses spatial and transform domain features of the target block jointly to filter out the majority of candidate modes. This is justified by examining the posterior error probability and the...

High efficiency video (HEVC) coding made its mark as a codec which compress with low bit rate than preceding that is H.264, but the factor stop HEVC from many applications complex encoding procedure. The distortion optimisation (RDO) cost calculation in consume calculations. In this paper, we propose method to cross out issue of calculations by replacing traditional inter-prediction procedure b...

Power Quality Disturbance (PQD) in a power grid distribution destroys the quality of to user. Thus, early detection disturbances is essential diagnose network before failure. Several may cause voltage sag, swell, or occurrence both. In proposed method deep recurrent neural (DRNN) used for classifying PQD as well Red Deer Optimization (RDO) algorithm optimizing weight from DRNN. Based on behavio...
