Abstract

MÉTODO E DISPOSITIVO DE CODIFICAÇÃO DE IMAGEM COM BASE EM FILTRAGEM. De acordo com as modalidades do presente documento, as informações para realizar a filtragem em loop através dos limites virtuais podem ser sinalizadas de forma eficaz. Por exemplo, a filtragem em loop pode ser executada com base na sinalização de informações relacionadas a se a filtragem em loop através de limites virtuais está habilitada ou não.
