Abstract :
Video compression is the contemporary coding techniques to reduce redundancy in raw video. This paper addresses the various visual quality metrics, in the digital image processing such as PSNR, MSE, and VQM. The encoder is used to convert the source data into compressed bytes. The decoder decodes the compression form into its original video sequence. Data compression is achieved by removing redundancy of video data. Video compression is a combination of spatial image compression and temporal Motion Compensation (MC). Both the compressions are vulnerable to redundant sequence. Lossy compression is based on the principle of removing subjective redundancy. Lossless compression is based on effective SR. The Video Quality Metric is used in the measurement of video sequences. The encoder and decoder pair is named by CODEC.
