A Novel Video Compression Approach Based on Underdetermined Blind Source Separation
This paper develops a new video compression approach based on underdetermined blind source separation. Underdetermined blind source separation, which can be used to efficiently enhance the video compression ratio, is combined with various off-the-shelf codecs in this paper. Combining with MPEG-2, video compression ratio could be improved slightly more than 33%. As for combing with H.264, 4X~12X...
متن کاملA Novel Video Compression Method Based on Underdetermined Blind Source Separation
If a piece of picture could contain a sequence of video frames, it is amazing. This paper develops a new video compression approach based on underdetermined blind source separation. Underdetermined blind source separation, which can be used to efficiently enhance the video compression ratio, is combined with various off-the-shelf codecs in this paper. Combining with MPEG2, video compression rat...
متن کاملFast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملTutorial on Multicast Video Streaming Techniques
This tutorial gives a survey of actual used techniques for multicast streaming video. We first discuss important issues in video streaming namely video compression techniques and video compression standards. We then present the challenges in multicast video streaming and we give a detailed description of recent proposals for multicast video streaming. We classify these solutions into four appro...
متن کاملRate Distortion Optimization in Video Compression
From Shannon’s classic rate distortion theory, we know that the main task of source coding or compression is to represent a source with the fewest number of bits possible for a given reproduction quality. Compression can be achieved with lossless techniques where the decompressed data is an exact copy of the original. However, this requirement also makes compression performance somewhat limited...
متن کاملThe Video Z-buffer: A Concept for Facilitating Monoscopic Image Compression by exploiting the 3-D Stereoscopic Depth map
Compression can be achieved by exploiting knowledge both internal and external to a given image or video source. In this paper, we present means for generating and exploiting the specific external knowledge of a 3D stereoscopic depth map of the given scene to compress the given monoscopic source. Several instances in which the depth map can potentially increase compression or provide improved f...
