Image processing involves enhancing the content of an image to extract information from it.
To process an image is to add meaning to it.

Speckle denoising
The goal is to replace the statistically outlying central pixel value with the average of the neighbors.
For this, we calculate the mean and the standard deviation of the values of the neighbors of the central pixel.
We then calculate the deviation between the central pixel and this average.
If this deviation is greater than the standard deviation (within a factor), then we consider that the value of the central pixel is outlying and we replace it with the average of the neighbors.

KUWAHARA denoising
The Kuwahara filter is a nonlinear smoothing filter used in image processing for adaptive noise reduction.
The Kuwahara filter applies smoothing to the image while preserving edges.
