METHOD AND APPARATUS FOR ENCODING OR DECODING AN IMAGE WITH INTER LAYER MOTION INFORMATION PREDICTION ACCORDING TO MOTION INFORMATION COMPRESSION SCHEME

摘要

The invention concerns a method, device, and computer program for motion vector prediction in scalable video encoder and decoder. It concerns the process to determine motion information predictor in the enhancement layer of a scalable encoding scheme also known as motion derivation process. It comprises a correction of the position in the reference layer used to pick-up the more relevant motion information available due to the compression scheme. Accordingly, motion information prediction is improved.
