The coordinates are integers, where `(x_min, y_min)` are the

`(x_max, y_max)` the bottom-right. By convention, the top-left
corner of the image is coordinate `(0, 0)`.
The probability, `prob`, is a float between 0 and 1, indicating the
confidence of the detection being correct.
The label of the object, `label`, may be either a string if the
