Abstract :
Pre-processing and post-processing algorithms improve on the performance of a video compression system especially by removing spurious noise and insignificant features from the original video data. So that this will increases compression efficiency, attenuates coding artifacts and mainly improving the quality of Video data. And more over existing video compression standards like MPEG, H.26x series are highly computationally expensive and hence they are not suitable for real time applications. Unlike video compression/decompression codec´s, video pre- and post-processing algorithms are not much standardized as of now. They might be different by end product. In addition, these algorithms are constantly being updated and new ones regularly appear. One more importance of these techniques are achieving low bit rate, high bit rate reduction while maintaining the best possible perceptual quality, post processing techniques provide one attractive solution. In result, the quality of the images is significantly improved.
