13.3 Object Detection

Object detection goes beyond classification by answering both 'what' and 'where'. For every object it finds, the model draws a bounding box and assigns a label and confidence. A single image can contain many objects of different classes, all detected at once.

Think of a traffic camera at a busy Addis Ababa junction. An object detector can count cars, buses, bajajs and pedestrians at the same time, each marked with its own box, which is impossible with plain classification.
