Vários algoritmos de varredura foram propostos para melhorar o desempenho da predição intra do codec H.264. Neste artigo, um esquema de varredura adaptativa é proposto para obter o ganho de codificação de entropia na codificação intra, onde os padrões de varredura são atualizados com base na distribuição probabilística dos coeficientes quantizados dos macroblocos anteriores, de modo que os zeros consecutivos estejam localizados na parte traseira do escaneado. fluxo de dados. Os resultados da simulação mostram que a redução média da taxa de bits é de cerca de 2.15% em condições de teste comuns.

Abstract: Various scanning algorithms have been proposed to enhance the performance of intra prediction of H.264 codec. In this paper, an adaptive scanning scheme is proposed to achieve the entropy coding gain in intra coding, where scanning patterns are updated based on the probabilistic distribution of quantized coefficients of previous macroblocks so that the consecutive zeros are located at the rear part of the scanned data stream. Simulation results show that the average bit-rate reduction is about 2.15% in common test conditions.
