<b>Fourier Filtering Denoising Based on Genetic Algorithms</b> As the traditional filtering methods may cause the problem of blur when applied on stripe lihike images, this paper raised a new method intending to solve the problem, and provided the process of the method development. The method, based on genetic algorithms as well as two dimensional Fourier transform, offered a new perspective to denoise an image with abundant components of high frequency, and is of certain significance. 2 D Fourier transform, genetic algorithms, autocorrelations 1142-1162 Issue-5 Volume-1 Jiahe Shi
