A formulation approach with hybrid wavelet transform for high efficiency video coding

摘要

Joint Collaborative Team of Video Coding(JCT-VC)collectively refined HEVC as a emerging standard with the compliance of former H.264/AVC. During the HEVC encoding process, the macro blocks of input video file are defined in each frame, between frames the motion vectors are estimated to generate compensated image. By Transform coding frame residuals of inter and intra predictions of HEVC, which possess distinct characters which contemplate residual frame. The residual frame information is performed using transformation, quantization and entropy coder, and the encoded bit stream is decoded to reconstruct the original video. In this paper, by using parallel transformation technique, the residual frame encoding and decoding is implemented for the improvement of HEVC. The results are presented with the use of proposed parallel transformation technique in the framework of the HEVC with algorithm-1 and algorithm-2 approach and performance results of our implementation shown better results in video quality metrics. Considering with the use of these two algorithms on HEVC transform, the performance analysis of PSNR is improved with existing Wavelet Transform.
