Abstract

"FILTRO DE DESBLOCAMENTO CONDICIONADO AO BRILHO DE PIXEL". Um codificador (100), um decodificador (200, 300), e um método correspondente (400) são apresentados para a codificação de dados de pixel como uma pluralidade de coeficientes de transformação de bloco e para a decodificação de coeficientes de transformação de bloco de modo a prover dados de pixel reconstruídos, o codificador e/ou decodificador inclui um filtro de desblocamento condicional (140, 240, 340) para a filtragem apenas das transições de bloco que satisfazem critérios de nível de brilho de pixel pré-selecionados, nos quais o método de filtro de desblocamento condicional (400) inclui a recepção (412) de pelo menos um primeiro pixel adjacente para uma transição de bloco, a provisão (414) de um sinal indicativo do brilho de pelo menos um primeiro pixel, a comparação (416, 418) do sinal de brilho com pelo menos um dentre um limite de brilho superior e um limite de brilho inferior, e a filtragem condicional (426) de uma pluralidade de pixéis adjacentes, incluindo o primeiro pixel na transição de bloco em resposta à comparação de brilho.
