Joint spatial-temporal-orientation-scale prediction and coding of motion vectors for rate-distortion-complexity optimized video coding

摘要

Several prediction and coding schemes are combined to optimize performance in terms of the rate-distortion-complexity tradeoffs. Certain schemes for temporal prediction and coding of Motion Vectors (MVs) are combined with a new coding paradigm of over complete wavelet video coding. Two prediction and coding schemes are set forth herein. A first prediction and coding scheme employs prediction across spatial scales. A second prediction and coding scheme employs a motion vector prediction and coding across different orientation sub-bands. A video coding scheme utilizes joint prediction and coding to optimize the rate, distortion and the complexity simultaneously.
