摘　　要：使用对傅里叶变换频谱进行空间滤波的方法,根据"切口"滤波器在频谱突变位置出现振铃现象的缺点,设计了基于"切口"滤波器的多点高斯滤波器.实验表明:使用该方法可以有效降低莫尔条纹对系统采集到图像质量的影响,得到的重构图像清晰,基本无振铃现象,可以满足系统需要.使用该方法运算量小、处理简单,能够由嵌入式系统完成.A novel approach using spatial filtering in the Fourier Spectrum is implemented. To avoid the ＂ ringing＂ phenomenon caused by the ＂notch filter＂, the multiple-point Gauss Filter based on the ＂ notch filter＂is designed. The experiments indicate that this approach can efficiently reduce the effects of Morie Fringes on the image quality,and the reconstructed images are clear and almost free from ＂ringing＂. This approach is simple to operate,has a small computing, and can be completed in embedded system.
