Prepares an image for use in the Compare Golden Template node.

image in

Reference to the golden template image to compare against during the golden template comparison phase.

learn mask

Optional 8-bit image of the same size as the golden template that specifies which regions and edges to ignore when comparing images to a golden template.

Use the following pixel values when constructing the mask:

  • 0—Maintains the default behavior.
  • 1—The corresponding pixel in the golden template is an edge and should be dilated according to the value of the edge thickness to ignore parameter of the Compare Golden Template node.
  • 2—The corresponding pixel in the golden template should always be ignored.

origin offset

Number of pixels the node shifts the origin of the golden template from the center of the golden template.

The default value is (0, 0), which sets the center of the golden template as the origin.

Default: (0, 0)

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

template image out

Reference to the learned golden template.

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
