It may be the person's name, gender, or something else.
Similarly, object detection involves the detection of a class of object and recognition performs the next level of classification, which tells which us the name of the object.
There is a vast number of applications that use object detection and recognition techniques. Here is a popular application that is going to be used in Amazon warehouses:
