Abstract

métodos e aparelho para melhoramento de cor de quadro com base em saliência. a presente divulgação se refere a métodos e dispositivos para processamento de exibição, incluindo um aparelho, por exemplo, uma dpu. o aparelho pode detectar pelo menos uma mudança de cena entre quadros sucessivos de uma pluralidade de quadros ou um número limite de quadros recebidos da pluralidade de quadros. o aparelho também pode gerar pelo menos um dentre um mapa de saliência, um mapa de segmentação de objeto ou um mapa de profundidade com base em uma imagem de amostragem reduzida de um primeiro quadro. o aparelho também pode aplicar uma cmf para um espaço de cores associado à pluralidade de quadros para a pluralidade de pixels em um ou mais quadros subsequentes da pluralidade de quadros, a cmf sendo aplicada até pelo menos uma dentre uma mudança de cena subsequente ou um número limite subsequente de quadros recebidos.
