In the landscape image above, the approximate coordinate values for the Left, Top, Right, and Bottom boundaries are 455, 191, 808, and 547 respectively (pixel coordinates). The width and height for the landscape image above is 1280 and 720 respectively.
### Activating TensorFlow
In this example, the Op Mode activates the TensorFlow object detector before waiting for the start command from the Driver Station. This is done so that the user can access the "Camera Stream" preview from the Driver Station menu while it waits for the start command. Also note that in this example, the op mode does not activate the Vuforia tracking feature, it only activates TensorFlow object detection. If you want to incorporate Vuforia image detection and tracking you will also need to activate (and later deactivate when you are done) the Vuforia tracking feature.

### Deactivating TensorFlow
When the example Op Mode is no longer active (i.e., when the user has pressed the stop button on the Driver Station) the Op Mode will attempt to deactivate the TensorFlow library before it's done. It's important to deactivate the library to free up system resources.
