Abstract

resumo "medição de qualidade de vídeo" uma implementação específica recebe um fluxo de bits e deriva parâmetros a partir do fluxo de bits. os parâmetros incluem parâmetros de quantização, parâmetros de imprevisibilidade de conteúdo, razões de blocos perdidos, razões de blocos propagados, distâncias de ocultação de erro, vetores de movimento, durações de congelamento, e taxas de quadro. utilizando esses parâmetros, um fator de distorção de compressão, um fator de distorção de fatiamento, e um fator de distorção de congelamento são estimados respectivamente para distorções que resultam de compressão de vídeo, uma ocultação de erro de modo de fatiamento, e uma ocultação de erro de modo de fatiamento congelamento. os fatores de distorção são então mapeados para uma marcação de qualidade de vídeo compósito. para aplicações com potência computacional limitada, a estimação de fatores de distorção pode ser simplificada. em particular, o fator de distorção de compressão, fator de distorção de fatiamento, e fator de distorção de congelamento podem ser previstos a partir de parâmetros de quantização, razões de blocos perdidos e durações de congelamento, respectivamente.
