模糊C均值方法，将模糊的方法用到K均值方法里面(Fuzzy C Means method, the fuzzy approach method which used the mean K)

用双线性变换法设计IIR数字滤波器 （1）用双线性变换法设计一个巴特沃斯低通IIR 数字滤波器。设计指标参数为：在通 带内频率低于0.2π 时，最大衰减小于1dB；在阻带内[0.3π ,π ] 频率区间上，最小衰减大于15dB。 （2）以0.02π 为采样间隔，打印出数字滤波器在频率区间[0,π / 2] 上的幅频响应特性 曲线。 （3）用所设计的滤波器对实际心电图信号采样序列（在本实验后面给出）进行仿真滤 波处理，并分别打印出滤波前后的心电图信号波形图，观察总结滤波作用与效果。 (err)

说明：  本程序展示了二维归一化互相关用于 &nbsp 模式匹配和目标跟踪。该程序提示用户选择感兴趣的（ROI）的区域和对同类目标进行跟踪的数目。归一化交叉相关图表明，当值已超过设定的阈值时目标就已经确定。(This demo illustrates the use of 2-D normalized cross-correlation for pattern matching and target tracking. The demo prompts the user to select the Region of Interest (ROI) and the number of similar targets to be tracked. The normalized cross correlation plot shows that when the value has exceeded the set threshold, the target has been identified.)
