A VIDEO COMPRESSION TECHNIQUE UTILIZING SPATIO-TEMPORAL LOWER COEFFICIENTS

With the advancement of communication in recent trends, video compression plays an important role in the transmission of information on social networking and for storage with limited memory capacity. Also the inadequate bandwidth for transmission and lower quality make video compression a serious phenomenon to consider in the field of communication. There is a need to improve the video compression process which can encode the video data with low computational complexity with better quality along with maintaining speed. In this work, a new technique is developed based on the block processing utilizing the lower coefficients between frames. The performance parameters such as Compression Ratio (CR) & Peak Signal to Noise Ratio (PSNR) are evaluated based on the algorithm for several standard video sequences. The proposed method results in higher compression rates as compared to the spatial block based compression technique. The simulation result shows that the proposed algorithm sustain faithful compression and reproduction of the video, preserving the picture quality.
