Abstract

In this paper, we present a perceptual-based encoding benchmarking of the H.264 Advanced Video Coding (AVC) inter-frame prediction variable block sizes for various spatial and temporal contents. This paper in order to quantify the impact on the video quality of the AVC inter-frame variable block sizes and the responsible prediction algorithm has disabled the motion estimation mechanism of the encoder and manually each block size is selected. Thus each time only one available block size out of the total seven is available to be searched for each MB and it is possible to examine the video quality impact of each block size independently to the remaining ones. The scope of this paper is to study if the use of sophisticated predictions algorithms and variable block sizes enhance the perceived quality of the encoded video signal or if there is not any significant quality degradation when the option of variable size is disabled.
