This package helps users draw bounding boxes around objects, without doing the clumsy math that you'd need to do for positioning the labels. It also has a few different types of visualizations you can use for labeling objects after identifying them.



The bounding box points are expected in the format: `(xmin, ymin, xmax, ymax)`

## There are *optional* functions that can draw multiple bounding boxes and/or write multiple labels on the same image, but it is advisable to use the above functions in a loop in order to have full control over your visualizations.



* bbv.draw_multiple_rectangles(img, bboxes)

* bbv.add_multiple_labels(img, labels, bboxes)

* bbv.add_multiple_T_labels(img, labels, bboxes)

* bbv.draw_multiple_flags_with_labels(img, labels, bboxes)



`bboxes` and `labels` are lists in the above examples.
