MULTIVIEWPOINT VIDEO CODING WITH MPEG-2 COMPATIBILITY

An efficient video coding scheme is presented as an extension of the M PEG-2 standard to accommodate the transmission of multiple viewpoint s equences on bandwidth-limited channels. With the goal of compression a nd speed, the proposed approach incorporates a variety of existing com puter graphics tools and techniques. Construction of each viewpoint im age is predicted using a combination of perspective projection of thre e-dimensional (3-D) models, texture mapping, and digital image warping . Immediate application of the coding specification is foreseeable in systems with hardware-based real-time rendering capabilities, thus pro viding fast and accurate constructions of multiple perspectives.
