Video image coding method, involves entropic coding of high space frequency signal related to current image by taking into account temporal context based on estimated vector movement

摘要

The method involves estimating movement between a current and reference instants, which correspond to respective current and reference images to provide a vector movement. A high space frequency signal relating to the current image is entropic coded by taking into account a temporal context, based on the vector movement. Parameters exploited for the calculation of the temporal context is parity of vector movement component. An independent claim is also included for a video encoder implementing a video image coding method.
