# Calculate Defect Map (G Dataflow)

Retrieves the information used to learn the template image.

## image in

Reference to the image in which you want to calculate defect maps.

## defect images in

Defect map for every match found. The defect map has a score for every pixel. The higher the score, the higher the probability of it being a defect. The score ranges from 0 to the square of the bit depth of the image. For example, an 8-bit image will have a score range from 0 to 65,535.

## window size

Size of the window that is used to compute the defect map.

## 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

## image out

Reference to the image input.

## defect images out

Defect map for every match found. The defect map has a score for every pixel. The higher the score, the higher the probability of it being a defect. The score ranges from 0 to the square of the bit depth of the image. For example, an 8-bit image will have a score range from 0 to 65,535.

## error out

Error information.

The node produces this output according to standard error behavior.
