本文在圆谐滤波器算法基础上,结合综合判别函数提出圆谐综合滤波器,解决传统匹配空间滤波器对输入目标的几何形变问题。对合成的滤波器进行了计算机模拟和光学相关实验,结果表明圆谐综合滤波器具有较强的三重不变光学图像识别能力。
In this paper, based on the circular harmonic filter algorithm, combined with the integrated discriminant function put forward a round-harmonic synthesis filter to solve the traditional matching of spatial filters on the input target geometry deformation. Computer simulation and optical correlation experiments on the synthesized filter show that the hybrid harmonic filter has strong ability of triple constant optical image recognition.
