Bilateral Filter
An edge-preserving smoother introduced by Tomasi and Manduchi in 1998 that blurs similar colors but not across sharp boundaries. It gives skin-smoothing and cartoon-like flattening without halos.
Spot it
- 01Smooth flat color areas
- 02Crisp preserved edges
- 03Waxy skin-like surfaces
Why it happens
Each pixel is averaged with neighbours weighted by both spatial closeness and color similarity, so pixels across a strong edge contribute almost nothing.
