Abstract
"ESQUEMA DE COMPRESSãO DE VìDEO UTILIZANDO ONDAS PEQUENAS". Elementos de dados, preferencialmente representativos de dados de vídeo, são logicamente divididos em blocos. De uma maneira no sentido de bits, cada bloco é inspecionado para determinar se os elementos de dados para aquele bloco pode ser representado em um formato altamente compacto. Se um dado bloco nao pode ser representado desta maneira, é subdividido em blocos possuindo dimensões menores. Este processo de identificar blocos adequados e subdividir é recursivamente repetido até dimensões de bloco mínimo serem alcançadas. O mesmo resultado pode ser alcançado através do uso de uma pluralidade de tabelas ascendentes (206) que são construídas formando repetitivamente tabelas de elementos de dados reduzidos. A pluralidade de tabelas ascendentes é atravessada e, baseado no elementos de dados reduzidos, blocos de dados são identificados que são suscetíveis ao formato altamente compacto. Transformações de onda pequena (204) são preferivelmente usadas para prover dados de vídeo para serem comprimidos.
