The dynamic and static performance index is greatly improved through decreasing quantization errors and combining with PI controller that operate nearby set point.
同时，通过削弱量化误差以及在设定点附近引入PI补偿控制器，提高了系统的动态、静态性能指标。
It provides optimal dynamic bit allocation for sub-bands of DWT and realizes adaptive quantization for wavelet coefficients. At last, it provides exact rate control for the coder.
该方法基于率失真曲线的精确理论模型，对小波分解后的不同子带提供最优的动态比特分配从而实现了小波系数的自适应量化编码，最后还实现了码率控制。
The input module includes data dynamic acquisition and quantization, which was divided into automatic monitoring index and artificial check index.
输入模块包括安全检测信息的动态采集和量化，分为自动监测和人工检查两类；
