Abstract

In today's electronic world, day-to-day activities are captured as a video and store it into a drive as their memory. The media processing 26 industries are growing suddenly and attain the peak level due to this drastic improvement of video needs. In this sense, video compression is the major part to deal with, because the size of video is usually large. The requirement to store the video into the drive requires huge space and memory. So, that a new technique is introduced in this paper, to compress the video. Video compression algorithms are widely used to reduce the huge size of video data, but they also introduce unpleasant visual artifacts due to the lossy compression. To obtain a high quality images/videos at the decoder side, a lot of compression artifact reduction algorithms have been proposed to generate artifact-free images in the past decades. Previously, manually designed filters and sparse coding based methods are proposed to solve this problem. In this project, Lucas Kanade based Optical flow detection for compression artifact reduction is proposed. The strategy first partitions every video outline into suspicious and evidently honest parts. So an optical stream coefficient is registered from each part. Phonies are found when an unordinary incline in the optical stream coefficient of the suspicious article is identified. An extensive experimental result on the Vimeo-90k and HEVC benchmark datasets demonstrate the effectiveness of the proposed method.
