Title
Using view interpolation for low bit rate video
Abstract
We demonstrate that in some situations, perceptual quality can be maintained using an approach based on synthesizing "virtual" images of a scene that match frames from a source video clip. We use this algorithm for interpolation of video frames in the time domain, using a small amount of information to construct an approximation of the original video. Our algorithm is well-suited for the limitations in bandwidth and complexity characteristic of wireless multimedia channels. Since the approach is based on estimating functions of the underlying camera motion parameters, it can capture relationships between image correspondences that extend across many (perhaps hundreds) of video frames. Each interpolated image can be rendered using only a few tens of bytes of side information, and the rendering process itself has low computational requirements. We present experimental results to demonstrate that for certain types of video, our algorithm can give significant perceptual improvement over MPEG-4 coded video at the same low bit rate
