cv2.boundingRect()

cv2.boundingRect() is a function in the OpenCV library of Python that is used for finding the minimum bounding rectangle for a given set of points or contours. The function takes a contour as input and returns four values, which are the coordinates of the top-left corner of the bounding rectangle (x,y), the width and the height of the rectangle. This function is typically used for object detection and tracking, as it helps in creating a bounding box around an object in an image or a video frame. The bounding box can then be used for various purposes like object recognition, object tracking, object segmentation, etc.
