摘要 提出了系数位上下文建模算法,利用它可先建立每个位平面的上下文,再直接进行编码,大大提高了编码的并行性。利用它还可以容易地实现一次性扫描的快速编码系统和位平面并行编码系统。 This paper proposed a coefficient-bit context modeling algorithm, Using this algorithm, the coefficient-bit context of all bit-planes could be produce before coding these bit-planes directly without calculating context,improving greatly the parallelism of coding. One-scan based fast JPEG2000 coding system and parallel bit-plane coding system also could be realized easily.
