Although exhaustively searching over all possible partition modes to choose the best coding mode for each macroblock improves the coding efficiency in H.264/AVC motion estimation, it has a lot of computational complexity. This paper proposes a fast algorithm to select the coding mode such that the number of candidate modes to be searched in motion estimation is significantly reduced and the coding...
In inter-frame coding of H.264/AVC standard, there are inter partition modes and intra modes to be taken into account for seeking best mode. Although it can achieve higher coding efficiency than any other previous coding standard, the computation complexity also increases significantly. In this work, based on the information of the histogram differences and rate part of rate-distortion optimization,...
This paper presents an error concealment algorithm for the H.264/AVC coding standard to recover the lost motion vector. The algorithm is based on an adaptive interpolation method. The interpolation weights are estimated by the technique of mean squared error minimization and the error is raised from horizontally and vertically interpolating the available neighbors of the lost motion vectors. The simulation...
In H.264/AVC video coding standard, it allows seven block sizes to perform the motion estimation/compensation. H.264/AVC standard also uses the full search to obtain the best performance. However, it spends a lot of computational time. In this paper, we propose an algorithm which adopts the fuzzy logic technique and edge energy information of the object to determine the most appropriate block size...
