I needed a new image filter for noisy image with accuracy approx 95 percent

I needed a new image filter for noisy image with accuracy approx 95 percent. I am doing research work in image processing. I needed to create image filter for noisy image. This new image filter accuracy should be at least 95 %. use: MATLAB language. (.m file ) For example : for c = 1 : 3 filter_image(:, :, c) = medfilt2(noisy_image(:, :, c), [3, 3]); end This is inbuilt image filter for noisy image. its a accuracy is approx 90-92%. or i can say in these word. [ssimval, ssimmap] = ssim(filtered_image,image); i.e. ssimval value is 0.90 so i need a brand new created image filter without using any builtin function with accuracy approx 95%.(ssimval value 0.95).
