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.
