contour2bbox

tomni.transformers.contour2bbox(contour: numpy.ndarray) → tuple[source]

Convert OpenCV contours into a bounding box format (xmin, ymin, xmax, ymax).

Parameters: contour (np.ndarray) – An array with coordinates defining the contour of an object.
Returns: A tuple containing the bounding box coordinates (xmin, ymin, xmax, ymax).
Return type: tuple

Example:

contour = np.array([[[3, 3]], [[3, 5]], [[5, 5]], [[5, 3]]], dtype=np.int32)
bbox = contour2bbox(contour)
print(bbox)
(3, 3, 6, 6)
