Fractional integral denoising algorithm of image based on Grümwald-letnikov

CHEN Li;School of Physics and Telecommunication Engineering,Shaanxi University of Technology;  
In order to remove the noise and to keep more details of image at the same time,analysis the frequency characteristic of the fractional integrals was made. The mathematical definition was analyzed,template coefficient was deduced,and the eight directions of fractional integral template was designed. The fractional integral denoising algorithm was constructed. The experimental results show that the algorithm can realize the image denoising well and retain texture information of the image,while the capability of denoising is better than the classical filter denoising algorithm.
