The main goal of the High Efficiency Video Coding (HEVC) standardization effort was to enable significantly improved compression performance relative to existing standards-in the range of 50% bit-rate reduction for equal perceptual video quality. In order to compare the performance and complexity without significant rate-distortion performance degradation,(More)
The H.264/AVC video coding standard aims to enable significantly improved compression performance compared to all existing video coding standards. In order to achieve this, a robust rate-distortion optimization (RDO) technique is employed to select best coding mode. This paper presents combined (intra and inter prediction) fast mode decision algorithm for(More)
In an attempt to reduce the computational time savings using H.264/AVC encoder, this paper seeks to provide that 23-35% can be achieved. The constraints are the following: Fidelity Range Amendment (FRExt) profile with correspondence tools, the skip prediction only for B pictures and rate-distortion optimization mode selection disabled. On the other hand, it(More)
This paper seeks to provide an approach to subjective video quality assessment in H.264/AVC standard. In general, methods for video content quality evaluation can be divided on objective and subjective one. While objective methodology uses mathematical methods for presenting human visual system (HVS), subjective method uses group of subjects (observers) to(More)
Understanding the molecular-level behavior of ionic liquids (ILs) at IL-solid interfaces is of fundamental importance with respect to their application in, for example, electrochemical systems and electronic devices. Using a model system, consisting of an imidazolium-based IL ([C2Mim][NTf2]) in contact with a sapphire substrate, we have approached this(More)

This paper presents selective intra coding and early inter skip fast mode decision algorithm for H.264/AVC and compares performance of H.264/AVC with prior standards. Video coding standard H.264/AVC provides gains in compression efficiency of up to 50% over a wide range of bit rates and video resolutions compared to previous standards. In order to achieve(More)
The H.264/AVC is the most recent standard of video compression/decompression for future broadband network. This standard was developed through the Joint Video Team (JVT) from the ITU-T Video Coding Experts Group and the ISO/IEC MPEG standardization committee. In this project H.264 decoder functional block such as Context based Binary arithmetic coding(More)
Despite considerable effort over the last decade, the interactions between solutes and solvents in the presence of electric fields have not yet been fully understood. A very useful manner in which to study these systems is through the application of molecular dynamics (MD) simulations. However, a number of MD studies have shown a tremendous sensitivity of(More)
