Descrizione

This effect/filter reduces chrominance noise.

Parametri

Parametro	Valore	Descrizione
Soglia Y+U+V	Intero	Set threshold for averaging chrominance values. Sum of absolute difference of Y, U and V pixel components of current pixel and neighbour pixels lower than this threshold will be used in averaging. Luma component is left unchanged and is copied to output. Default value is 30. Allowed range is from 1 to 200.
Dimensione orizzontale / verticale	Intero	Set horizontal / vertical radius of rectangle used for averaging. Allowed range is from 1 to 100. Default value is 5.
Passo orizzontale	Intero	Set horizontal step when averaging. Default value is 1. Allowed range is from 1 to 50. Mostly useful to speed-up filtering.
Soglia Y / U / V	Intero	Set Y / U / V threshold for averaging chrominance values. Set finer control for max allowed difference between Y / U / V components of current pixel and neighbour pixels. Default value is 200. Allowed range is from 1 to 200.
