Compare the final result with the first frame,and you will see a reduction in noise. Unfortunately this simple method is not robust to camera and scene motions.

The simplest way to reduce noise is to slightly blur the image, for example using a gaussian or median filter.

You can see reduction in noise. Unfortunately this simple method is not robust to camera and scene motions. Also often there is only one noisy image available.

Denoising is done to remove unwanted noise from image to analyze it in better form. The final PSNR values(Peak signal-to-noise ratio) to frames output are: ...
