We derive tight bounds on the ratio between the number of box intersections and the number of object intersections. Confirming intuition, we show that the performance of bounding boxes improves significantly when the underlying objects are all convex. In particular, the ratio is Θ(α{sup}(l-l...

A bounding box isan imaginary rectangle that serves as a point of reference for object detection and creates a collision box for that object. Data annotators draw these rectangles over images, outlining the object of interest within each image by defining its X and Y coordinates. ...
Bounding boxes are always aligned to the world's axes; they never rotate. This is presumably because of their use for collision detection of players: it would be impossible to turn around in a tight corridor if the four corners of your bounding box rotated with you. Axis-aligned boxes are...
There are a few drawbacks of using the bounding box for collision detection. Rotating a bounding box causes it to no longer be axis aligned. Because of this, if you rotate a model being bounded, you will need to recreate the bounding box. Doing so can be slow, since all the points in...
The bounding box binary tree is traversed from the root node in the intersection test. The two objects are not intersected if the root nodes of their bounding box are not intersected, otherwise, the bounding box collision detection at the next level is carried out. If two bounding boxes of...

You could say that the bounding box is an abstract rectangle that serves as a reference point for object detection and generates a collision box for that object. These rectangles get drawn over images by data annotators, who identify the X and Y coordinates of the point of interest inside ev...
