Abstract

a presente invenção refere-se a valores estatísticos que são calculados com base em imagens de origem recebidas. uma função de remodelagem adaptativa é selecionada para uma ou mais imagens de origem, com base nos um ou mais valores estatísticos. uma porção de conteúdo de vídeo de origem é remodelada de maneira adaptativa, com base na função de remodelagem adaptativa selecionada, para gerar uma porção de conteúdo de vídeo remodelado. a porção de conteúdo de vídeo de origem é representada pelas uma ou mais imagens de origem. uma aproximação de um inverso da função de remodelagem adaptativa é selecionada. o conteúdo de vídeo remodelado e um conjunto de parâmetros de remodelagem adaptativa que definem a aproximação do inverso da função de remodelagem adaptativa selecionada são codificados um sinal de vídeo remodelado. o sinal de vídeo remodelado pode ser processado por um dispositivo receptor a jusante para gerar uma versão de imagens de origem reconstruída, por exemplo, para apresentação em um dispositivo de exibição.
