DEBLOCKING FILTER BASED ARTIFACT REDUCTION USING PSEUDO RANDOM NOISE MASKING

In this Project, we propose an algorithm for block artifact reduction for which Pseudo random noise masking is used. In H.264 Video Compression Standard, a Deblocking filter is implemented to reduce the quantization noise around the block boundaries. But there would still remain artifacts within blocks. These artifacts are known as Contour artifacts. These Contour artifacts further be reduced by our Proposed Pseudo Random Noise Masking Method. H.264/AVC is a new international standard for the compression of natural video images, in which a deblocking filter has been adopted to remove blocking artifacts. Making good use of data dependence between neighboring 4x4 blocks, our design increases the throughput of the filter processing.
