Abstract

método e aparelho para armazenamento de informações de movimento. um método de armazenar informações de movimento compreende: determinar uma distância entre um conjunto de amostras no bloco atual e a fronteira comum; e comparar a distância com um limiar para determinar se terceiras informações de movimento estão armazenadas para o conjunto de amostras, em que as terceiras informações de movimento são derivadas pelas primeiras informações de movimento e pelas segundas informações de movimento.
