The Kuwahara filter in rust.
The Kuwahara filter is a non-linear filter used for image smoothing while preserving edges. It divides the image into overlapping square regions and computes the mean and variance of pixel values within each region. Then, it selects the region with the smallest variance and replaces all pixels within that region with the mean value of those pixels.
