The simulation results show that the algorithm based on expectation prediction value achieves higher prediction hit rate of cache and lower average waiting delay than the algorithm based on FIFO.
仿真实验结果表明，该算法与传统的FIFO算法相比较，提高了缓存的预测命中率，减少了用户平均等待延迟。
A key difference is that this algorithm does not give the same value at the sampling point but gives the same average value in unit area of each pixel.
此算法的关键不同点在于不是让算法结果在采样点的值等于原采样值，而是在一个象素大小的单位面积上得到的平均值等于原采样值。
Meanwhile, through the privacy key analysis, the histogram analysis, the information entropy, the average value of gray change and the relevant analysis, the security of this algorithm is very high.
同时通过具体的密钥空间分析、直方图分析、信息熵、灰度变化平均值和相关性分析显示，该算法具有很高的安全性能。
