Requires: NI Vision Development Module
Adds an object instance from the list of instances stored in the object tracking session.

Object Tracking Session In is a reference to the object tracking session. |

Image is the image containing an object to track. |

ROI Descriptor specifies the region of the image in which to track objects. This region must be a single rectangle or rotated rectangle contour. By default, the VI tracks the entire image.

error in (no error) describes the error status before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
