摘　　要：为消除屏拍摄图像摩尔条纹,分析摩尔条纹形成机制,得出屏摄图像频域特征。利用傅里叶变换,将屏摄图像转换到频域,根据屏摄图像的频域特征,设计算法消除引发摩尔条纹的频域信息。结果表明,该方法可以有效地消除屏摄图像摩尔条纹,是一种简单有效地消除屏摄图像摩尔条纹的方法,且对原始图的高频信息影响较小。In order to eliminate moire fringes in screen-shot images,the formation mechanism of moire fringes is analyzed,and the frequency domain characteristics of screen-shot images are obtained.Fourier transform is used to transform the screen image into the frequency domain.According to the frequency domain characteristics of the screen image,an algorithm is designed to eliminate the frequency domain information that causes moire fringes.The results show that this method can effectively eliminate moire fringes in screen images,and is a simple and effective method to eliminate moire fringes in screen images,and the high-frequency information of the original image has little influence.
