Bounding Box Annotation 

It involves the drawing of a bounding box over an object, usually an image, and labeling it with an object class. This is important for high quality data training for diverse Artificial Intelligence systems. For the data to be accurate and the machine learning to be precise, the bounding boxes have to be drawn tightly around the object with no loose ends. It is mostly used for detecting objects for autonomous vehicles and tagging for retail and ecommerce.
