Abstract
Video Compression is about reducing and removing redundant video data so that a digital video file can be effectively sent and stored. The MVCWT deals with video compression in an efficient manner. It focuses on performance, time as well as the compression ratio using effective transforms and coding techniques. In Motion Estimation, Block matching algorithm is being used to determine the moving vector of each block. We have analyzed various block matching algorithms. Adaptive Block Matching Algorithm method is used for finding the moving vectors. Motion compensation is done for reconstructing the video from the moving vector. Both the Motion Estimation and Motion Compensation will be done using Wavelet Transform. Huffman variable length coding is being used for encoding and decoding process. Compression rate depends on two factors such as PSNR value and the bit rate. The bit rate should be less and the PSNR value should be high.
