Abstract

La presente invencion proporciona metodos y aparatos para la estimacion del movimiento de sub-pel de un bloque de pixeles. Los puntos de busqueda que son redundantes entre las diferentes busquedas de sub-pel y pel completo durante el proceso de estimacion de movimiento de un bloque de pixeles son descartados. Los costos de cotejo para los bloques o sub-bloques de cada uno de los puntos de busqueda redundantes no son calculados y por lo tanto, no son almacenados.
