snake
- 在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置,先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心,该圆心只要能落在瞳孔内部即可。然后以该伪圆心为中心,在其周围等角度间隔地取N个点作为初始的snake基准点,按照snake 的运行机制不断进化,直到虹膜的内边界为止。最后,计算进化后的snake形心和snake上的控制点与该形心的距离,取其平均值作为瞳孔的半径,动态轮廓模型的形心作为瞳孔的圆心,即可准确定位出虹膜内边界的位置。实验表明,与常见的定位方

DSPII_USTC_01
- 传统的宽带信号中抑制正弦干扰的方法是采用陷波器(notch filter),为此需要精确知道干扰正弦的频率.然而当干扰正弦频率是缓慢变化时,且选频率特性要求十分尖锐时,则最好采用自适应噪声抵消的方法.下图是用一个二阶FIR的LMS自适应滤波器消除正弦干扰的一个方案。该代码实现了以下功能: 1) 借助MATLAB画出了滤波器的误差性能曲面和误差性能曲面的等值曲线; 2) 给出了最陡下降法以及LMS算法的计算公式; 3) 用MATLAB产生了方差为0.05, 均值为0白噪音S(n),并
