- 基于交叉累计剩余熵的图像配准中插值方法的改进 交叉累计剩余熵(CCRE)比传统互信息在配准强噪声图像时更具优势,但采用部分体积(PV)插值的CCRE在网格点容易产生局部极值,不利于变换参数的优化。针对该问题,研究基于3阶B样条函数的PV插值(BPV)、哈宁窗sinc函数的PV插值(HPV)和Blackman-Harris窗sinc函数的PV插值(BHPV)方法在CCRE中的应用,提出一种新的插值方法。该方法采用灵活的邻域中心,
FIR
- 1、验证窗函数 N 变化时,验证其频谱主瓣副瓣比、主瓣宽度的变化。 a)矩形窗函数的 N 变化时,验证其其频谱主瓣副瓣幅度比基本不会发生变化, 而主瓣宽度将会变窄。这说明,当用矩形窗函数设计滤波器时,增大 N 不能使 得阻带衰减减小,但能够减小过渡带。 b)再选取其他的窗如 hamming/hanning 窗,验证当 N 变化时,其频谱主瓣宽 度变化、主瓣副瓣比值变化情况。 2、用窗函数法设计线性相位 FIR 低通,通带截止
