Frequently Asked Questions

What is the Kuwahara filter?

Kuwahara is a non-linear smoothing filter that averages pixels within the most uniform quadrant of a local neighborhood. It blurs smooth regions while preserving edges, producing a painterly effect.

What is the difference vs Gaussian blur?

Gaussian blur smooths edges; Kuwahara preserves them. That's why Kuwahara produces the distinctive oil-painting look instead of a defocused appearance.

What is generalized Kuwahara?

The generalized version divides the neighborhood into N overlapping sectors (8 or 16) instead of just 4 quadrants, producing smoother, more natural output.
