Computes a ratio between two images.

Each pixel in image src a is multiplied by the integer value specified in constant before being divided by the equivalent pixel found in image src b. To avoid losing information, a temporary variable giving higher definition is used to perform the operation. If the background is lighter than the image, this node can correct the background. In a background correction image, image src a is the acquired image, and image src b is the light background

image src a

Reference to the first source image.

datatype_icon

image dst

Reference to the destination image.

datatype_icon

image src b

Reference to the second source image.

constant

Value multiplied by each pixel in image src a before each pixel in image src a is divided by the equivalent pixel in image src b.

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

image dst out

Reference to the destination image that receives the processing results of the node.

If image dst is connected, image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image src a.

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
