Description

Luma Radius

Float

Number in the range [0.1,5.0] that specifies the variance of the gaussian filter used to blur the image (slower if larger). Default value is 1.0.

Luma Strength

Float

Number in the range [-1.0,1.0] that configures the blurring. A value included in [0.0,1.0] will blur the image whereas a value included in [-1.0,0.0] will sharpen the image. Default value is 1.0.

Luma Threshold

Integer

Used as a coefficient to determine whether a pixel should be blurred or not. The value must be an integer in the range [-30,30]. A value of 0 will filter all the image, a value included in [0,30] will filter flat areas and a value included in [-30,0] will filter edges. Default value is 0.

Chroma Radius

Float

Same as Luma Radius. Default value is what is defined for Luma Radius.

Chroma Strength

Float

Same as Luma Strength. Default value is what is defined for Luma Strength.

Chroma Threshold

Integer

Same as Luma Threshold. Default value is what is defined for Luma Threshold.
