Image Denoise Based on Modified Fractal Model
Guoqiang Wei · Wuhan University Journal · 2004
Based on the principle of Iterated Functions Systems of Fractal, and in order to filter Gaussian noise in the degraded image and preserve, at the same time, the details of image, in this paper, we advance a improved denoising algorithm based on fractal model. Its characteristics are shown as following:Replacing spatial seaching matching algorithm by s m algorithm in frequency domain, it has much quicker speed of matching and convergence; It can auto adjust parameters while in doing matching. It is shown that the new scheme can preserve the details of the image effectively and reduce the block effect.
