Abstract

predição de vetor de movimento e refinamento. a invenção refere-se a um método para codificação de um bloco atual de uma sequência de imagens compreendendo as etapas seguintes: - determinar (20,30) pelo menos um vetor de movimento candidato associado com um bloco vizinho do dito bloco atual, determinar (24,34) um vetor de movimento da predição a partir do vetor de movimento candidato e - codificar (26,36) o bloco atual a partir do vetor de movimento de predição. vantajosamente, o vetor de movimento da predição é determinado de acordo com as etapas seguintes - determinar (22,32), para o vetor de movimento candidato, um vetor de movimento corretivo, de modo a minimizar a distorção calculada entre o bloco vizinho sucessivamente codificado e reconstruído e um movimento do bloco de predição compensado por o pelo menos um vetor de movimento candidato modificado pelo vetor de movimento corretivo e determinar (24,34) o vetor de movimento da predição a partir do vetor de movimento candidato modificado pelo vetor de movimento corretivo.
