Flat Field Parameters (Flat Field Image Streaming) (G Dataflow)

Last Modified: October 26, 2017

Returns the median of the supplied image or images.

If the flat field image and dark field image are connected, this node returns the median of the dark field image subtracted from the flat field image. If only the flat field image is connected, this node returns the median of the flat field image.

connector_pane_image
datatype_icon

flat field image in

Flat field image.

datatype_icon

dark field image in

Dark field image.

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

datatype_icon

flat field image out

Estimated flat field image.

datatype_icon

dark field image out

Estimated dark field image.

datatype_icon

median

median is the median intensity value of the reconstructed flat field image. Pass this parameter as an input to the IMAQ FPGA Flat Field Correction VI.

datatype_icon

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
