描述

Y+U+V Threshold

整數

Set threshold for averaging chrominance values. Sum of absolute difference of Y, U and V pixel components of current pixel and neighbor 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.

Horizontal / Vertical size

整數

Set horizontal / vertical radius of rectangle used for averaging. Allowed range is from 1 to 100. Default value is 5.

Horizontal step

整數

Set horizontal step when averaging. Default value is 1. Allowed range is from 1 to 50. Mostly useful to speed-up filtering.

Y / U / V threshold

整數

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 neighbor pixels. Default value is 200. Allowed range is from 1 to 200.

距離

選取

Set distance type used in calculations

可以使用以下選項：

Distance

Manhatten

absolute difference (default)

Euclidean

difference squared
