A Non-linear Filter De-noising Algorithm for Images Based on Discrete Fourier Transform

LIU Zhu-hua~1,ZOU Dao-wen~2,DENG Cheng-zhi~1,WANG Sheng-qian~2,XIONG Xiao-hua~1 niversity, 330027,China; 2.Jingxi Science & Technology Normal College, Applied Physics Department, Nanchang, 330013,China)  
Although the traditional linear filtering in frequency domain can reduce noise, it also blurs the edge details. In this paper, we propose a non-linear filtering algorithm, which denoises image through containing the big module coefficients in the frequency domain. Experiment resuct shows that this new algorithm can preserve the image details as well as remove image noise.
