Name Type Range Default Description
inImageFil.ImageInput image.
inRoiFtl.Optional<Fil.Region>Range of output pixels to be computed. Default value: ftl::NIL.
inStdDevfloat<0.0f, INF>3.0fSmoothing standard deviation for the smaller kernel. Default value: 3.0f.
inStdDevRatiofloat<1.0f, INF>1.6fDefines how many times larger is the second kernel. Default value: 1.6f.
