Add Classifier Sample (G Dataflow)

Last Modified: June 25, 2019

Assigns a new image sample to the specified class in classifier session in.

The new sample is based on an ROI in the image and is assigned to a specific class.

ROI descriptor

Region of interest specifying the location of the sample in the image.

The ROI must be one or more closed contours. If ROI descriptor is empty or not connected, the entire image is considered to be the region. For best performance, use only one rectangle or one rotated rectangle per sample.

datatype_icon

Global Rectangle

Coordinates of the bounding rectangle.

datatype_icon

Contours

Individual shapes that define an ROI.

datatype_icon

ID

Object specifying if contour is the external or internal edge of an ROI.

datatype_icon

Type

Shape type of the contour.

datatype_icon

Coordinates

Relative position of the contour.

datatype_icon

classifier session in

Reference to the classifier session on which the node operates.

datatype_icon

image in

Reference to the source image.

datatype_icon

class

Class to which you want to assign the sample.

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

classifier session out

Reference to the classifier session the node creates.

datatype_icon

image out

Reference to the source image.

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
