Abstract

"ESTIMATIVA DE MOVIMENTO COM COMPARAçãO DE BLOCOS DE BUSCA RáPIDA". Trata-se de um codificador de vídeo e de um método correspondente para codificar dados de sinal de vídeo para um bloco de imagens e um índice de imagem de referência específico com a finalidade de predizer o bloco de imagens, em que o codificador (100) inclui um estimador de movimento de blocos de busca rápida (180) para fornecer vetores de movimento que correspondem a pelo menos uma imagem de referência específica, o estimador de movimento compreendendo uma parte de comparação de blocos de busca rápida para efetuar comparação de blocos de busca rápida enquanto se excluem os pontos de busca não ótimos de acordo com uma comparação da normalização dos pixels do bloco de imagens com a normalização dos pixels da imagem de referência, a parte de comparação de blocos de busca rápida tendo uma saída que responde a pelo menos uma imagem de referência específica; e o método correspondente (200) inclui receber um bloco de imagens substancialmente não comprimido (212), efetuar comparação de blocos (214) no bloco de imagens em correspondência com pelo menos uma imagem de referência específica enquanto se excluem os pontos de busca não ótimos de acordo com uma comparação da normalização dos pixels do bloco de imagens com a normalização dos pixels da imagem de referência, computar (216) os vetores de movimento correspondentes à diferença entre o bloco de imagens e pelo menos uma imagem de referência específica e fazer compensação de movimento (218) da imagem de referência especifica em correspondência com os vetores de movimento.
