In order to overcome these disadvantages, a new method of early predicting AZC blocks is proposed in this paper. In this method, no additional computation is needed and the threshold can be changed with the quantization level.

• 针对这些缺点；该文提出了一种新的全零系数块的判别方法；它具有能随量化级的变化自适应地调整全零块的判断阈值、无需任何附加运算和对图像序列内容复杂程度不敏感的优点；将该方法应用于H.
