Abstract: Extracting the clear fundus images information is a prerequisite for diagnosing the patients' conditions exactly in clinic. This paper adopts respectively de-noising algorithm based on multi-scale and that based on median filter to process real fundus images. It gives the LMLSD algorithm based on Gaussian wave extraction, which is used to estimate SNR (Signal-to-Noise) of the processed images and give an objective quantitative evaluation to treatment effect of the above two denoising algorithms. The results s…
