An Efficient Technique for Error-Free Implementation of H.264 Using Algebraic Integer Encoding

Video coding technology plays a key role in various multimedia applications. H.264 is the newest video coding standard and has achieved a significant improvement in coding efficiency. The 4*4 integer transform, as one of the key techniques in H.264 video compression standard, is very important for the whole performance of H.264 codec. In this paper we propose a novel algorithm for fast and error-free (infinite-precision) implementation of H.264 based on algebraic integer-encoding scheme. The proposed algorithm has regular structure. Simulation results show that this algorithm will result in reduction of computation complexity while enhancing the quality of obtained image simultaneously. Determining the quality of an image is an open problem that is highly dependent on the specific application that this image will be used for. We propose new measuring quantities for image quality.
