Abstract :
The intra prediction techniques employed in H.264 predict the intensities of the pixels of the current block from the neighboring pixels. Coding of intra slices requires a large number of bits. Therefore, to improve the coding efficiency, another intra prediction technique is applied with several proposed enhancement techniques including best match prediction, multiple best matches, novel padding method, skip mode, etc. Experimental results show that the coding efficiency can be improved significantly, and more than 1 dB and 0.6 dB gain in PSNR can be achieved for intra and hybrid coding, respectively.
