Understanding Bounding Boxes in Computer Vision =============== In computer vision, bounding boxes are used to describe the location and extent of objects within an image or video frame. A bounding box is typically represented as a rectangle with its top-left corner at position $(x, y)$ and its width and height dimensions $w$ and $h$, respectively. The region inside this rectangle represents the object being identified. Understanding the Problem Given a DataFrame with columns left, top, width, and height, we need to sort the products based on their bounding boxes from left to right and top to bottom.
