振幅补偿匹配滤波中的旋转和尺度变化效应
The effects of rotation and scale change with amplitude-compensated filter
摘要
本文研究了振幅补偿匹配滤波的旋转效应和尺度变化效应.计算机模拟的结果表明,这种滤波法对输入信号的旋转变化和尺度缩放变化,相对于传统的匹配滤波法及仅相位滤波法要敏感得多.文中还给出了这三和滤波下的相关峰值与旋转角度及尺度因子的关系曲线.
Abstract
In this paper, rotation and scaling properties with an amplitude-compensated matched titer is presented. Computer simulations show that this kind of filter is much more sensitive as compared to a matched spatial filter or a phase-only one. Correlations against rotation angle and scaling factor for all the three filters are also presented.
