Abstract

?detecção de região estática baseada em bloco para processamento de vídeo? trata-se de métodos, aparelho, sistemas e artigos de manufatura para realizar detecção de região estática baseada em bloco para processamento de vídeo. os métodos de processamento de vídeo exemplificativos revelados incluem segmentar pixels em um primeiro quadro de uma sequência de vídeo em uma primeira pluralidade de blocos de pixel. tais métodos exemplificativos podem também incluir processar a primeira pluralidade de blocos de pixel e uma segunda pluralidade de blocos de pixel correspondentes a um segundo quadro anterior da sequência de vídeo para criar, com base em um primeiro critério, um mapa que identifica um ou mais blocos estáticos de pixel na primeira pluralidade de blocos de pixel. tais métodos exemplificativos podem incluir, ainda, identificar, com base no mapa, uma região estática no primeiro quadro da sequência de vídeo.
