Abstract

resumo "medição de qualidade de vídeo considerando múltiplos artefatos" uma implementação particular determina níveis de distorção objetivos (d,), respectivamente para uma pluralidade de tipos de artefatos. os níveis de distorção objetivos são alinhados para garantir que o mesmo nível de distorção de tipos dife-rentes de artefatos corresponda com o mesmo nível de distorção percebido. os ní-veis de distorção alinhados (d,’) são classificados para obter níveis de distorção classificados (d,”). os níveis de distorção classificados são então associados juntos em um nível de distorção geral ou uma métrica de qualidade geral. os níveis de dis-torção classificados podem ser associados usando uma soma ponderada, em que o peso é maior quando o nível de distorção classificado é maior.
