This filter will find the average color of the image and then fill the image with that color.

This filter is used to remove digital noise from a photo. You can keep all the settings in their default values and just move the "Noise scale" a little bit each time to the right until the desired results are reached. Please note that this filter is slow and may takes a long time to complete for large image. You may try it on a small part of the image and see which noise scale gives the best results and then apply this value to the original image.

This filter is similar to Denoise filter and is used to remove digital noise. Start by moving the "Sigma p" to the right a little bit and check the results while keeping other settings at their default values. Please note that this filter is also slow and may takes a long time to complete for large image. You may try it on a small part of the image and see which value of the "Sigma p" gives the best results and then apply this value to the original image.
