Abstract

"DISPOSITIVO E MéTODO DE BUSCA DE UM VETOR DE MOVIMENTO E MEIO DE GRAVAçãO". Em um dispositivo de busca de vetor de movimento que incluindo porção de busca de vetor de movimento (101-110) suprida com um sinal de figura introduzida representativo de uma sucessão de figuras para dividir cada uma das figuras do sinal de figura introduzida em blocos e proceder à busca de um vetor de movimento como um vetor de movimento buscado para cada bloco de cada uma das figuras em uma área de busca do sinal de figura introduzida para cada bloco de cada uma das figuras, uma porção de aprendizado (113, 313) aprende as tendências dos vetores de movimento buscados para as figuras anteriores anteriormente à figura corrente das figuras do sinal de figura introduzida para produzir uma informação de tendência representativa das tendências. Uma porção de determinação (114) determina a área de busca de cada bloco da figura corrente com base na informação de tendência para fazer a porção de busca de vetor de movimento proceder à busca do vetor de movimento como o vetor de movimento buscado para cada bloco da figura corrente na área de busca de cada bloco da figura corrente.
