Note: Show Gradient Sign works only when just one of the Enhance Edge settings is True.
Gaussian Filter
In the Image Filtering Drawer
The Gaussian Filter tool performs filtering of pixel grey levels within an ROI to smooth an image. A filter
area is defined and used to sequentially process an area that size within the ROI. Pixels at the center of the
filter area are weighted more than those further away (a Gaussian curve). This results in more precise
smoothing. The effect is similar to changing the camera focus. This tool’s filtering is more precise but
slower than the Average Filter tool.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space
Shape List The desired region of the image to process. If no shape is defined, the
entire image is processed.
Enhance 0 Degree
Edges
If True, edges that are not rotated are enhanced
Enhance 45 Degree
Edges
If True, edges that are rotated 45 degrees are enhanced
Enhance 90 Degree
Edges
If True, edges that are rotated 90 degrees are enhanced
Enhance 135
Degree Edges
If True, edges that are rotated 135 degrees are enhanced
Show Gradient Sign
If Single Direction
Enabled
If True, and only one Enhance Degree Edges setting is True, then falling
edges are shown as dark and rising edges are shown as bright, giving
the image an embossed look.
