Title
(EN) PARTIAL PRUNING METHOD FOR INTER PREDICTION
(FR) PROCÉDÉ D'ÉLAGAGE PARTIEL POUR PRÉDICTION INTER
Abstract
(EN)
Techniques for video encoding and decoding are described. An example method of video processing is disclosed. The method includes classifying motion candidates in a candidate list into a plurality of categories of motion candidates, each category being assigned a corresponding pruning rule; performing pruning or skipping the pruning of the motion candidates in the candidate list based on the corresponding pruning rule, the pruning being applied to determine whether to insert motion candidates from the candidate list into a final candidate list for a current block; and performing a video processing on the current block based on the final candidate list.

L'invention concerne des techniques de codage et de décodage vidéo. L'invention concerne également un procédé donné à titre d'exemple de traitement vidéo. Le procédé consiste à classifier des candidats de mouvement dans une liste de candidats en une pluralité de catégories de candidats de mouvement, chaque catégorie étant attribuée à une règle d'élagage correspondante; effectuer un élagage ou sauter l'élagage des candidats de mouvement dans la liste de candidats sur la base de la règle d'élagage correspondante, l'élagage étant appliqué pour déterminer s'il faut insérer des candidats de mouvement de la liste de candidats dans une liste de candidats finale pour un bloc actuel; et effectuer un traitement vidéo sur le bloc actuel sur la base de la liste de candidats finale.
