Any algorithm that provides predicted bounding boxes as output can be evaluated using IoU. The returned value is a collection of DOMRect objects, one. To draw a bounding box between two contours, you would just have to pick points on the contours and feed them into the boundingRect() method. Returns: Real Description. This PR finds the smallest bounding box that fits the ellipse, and constrains the shape parameter before calling _ellipse_in_shape. Such a box is called an axis-aligned box and since it will often be a bounding box (or bounding volume) which we also designate by the acronym AABB (axis-aligned bounding box). Alternatively, you can draw it onto an existing Mat with the Imgproc. Straight Bounding Rectangle¶ It is a straight rectangle, it doesn't consider the rotation of the object. Example: What I want is the most left. It's a convenient way to show what is currently selected before applying the next operation. To emphasize the utility of the bounding box, an organic shape will be used.
