 - Note: I have already provided the annotated xml file for this example, make sure you rename/create as per your wish in the command.
 - Start imglab: ```$ imglab face_detector/newfile.xml```. The following GUI should open up:

 - To start labeling, hold the 'shift' key and drag a bounding box around the object. 
 - It is important that all the examples of objects are labeled to avoid false positives/bad accuracies. 
 
 > If there is an ROI that you are unsure about and want to be ignored entirely during the training process, simply double-click the bounding box and press the 'i' key. This will cross out the bounding box and mark it as 'ignored'.
