Abstract

1/1 resumo "aperfeiçoamento de rendimento para codificação de nível de coeficiente cabac". essa descrição propõe várias técnicas para limitação do número de compartimentos que são codificados utilizando-se um modelo de contexto adaptativo com a codificação aritmética binária adaptativa de contexto (cabac). em particular, essa descrição propõe limitar o número de compartimentos que utilizam cabac para codificação de informação de nível dos coeficientes de transformação em um processo de codificação de vídeo.legendas dos desenhos
