WebBounding boxes are rectangular boxes used to define the location of the target object. They can be determined by the 𝑥 and 𝑦 axis coordinates in the upper-left corner and the 𝑥 and 𝑦 axis coordinates in the lower-right corner of the rectangle. Bounding boxes are generally used in object detection and localisation tasks.
