Abstract

comparação de codificadores/decodificadores de vídeo usando codificação baseada em plano e uma métrica de qualidade visual perceptual. em várias modalidades, um aplicativo de comparação de codificador compara o desempenho de diferentes codificadores configurados. em operação, o aplicativo de comparação de codificador gera um primeiro casco convexo global de pontos de codificação de vídeo com base em um primeiro codificador configurado e um conjunto de subsequências incluídas em uma sequência de vídeos de origem. cada ponto de codificação de vídeo está associado a uma versão codificada diferente da sequência de vídeos de origem. o aplicativo de comparação de codificador também gera um segundo casco convexo global de pontos de codificação de vídeo com base em um segundo codificador configurado e nas subsequências. subsequentemente, o aplicativo de configuração de codificador calcula um valor de desempenho para uma métrica de comparação de codificação com base no primeiro casco convexo global e no segundo casco convexo global. notavelmente, o primeiro valor de desempenho estima uma diferença de desempenho entre o primeiro codificador configurado e o segundo codificador configurado.comparison of video encoders/decoders using plane-based encoding and a visual perceptual quality metric. in various embodiments, an encoder comparison application compares the performance of different configured encoders. in operation, the encoder comparison application generates a first global convex hull of video encoding points based on a configured first encoder and a set of subsequences included in a source video sequence. each video encoding point is associated with a different encoded version of the source video stream. the encoder comparison application also generates a second global convex hull of video encoder points based on a configured second encoder and substrings. subsequently, the encoder configuration application calculates a performance value for an encoding comparison metric based on the first global convex hull and the second global convex hull. notably, the first performance value estimates a performance difference between the first configured encoder and the second configured encoder.
