bbox-visualizer

Documentation Status License: MIT PyPI version Downloads

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)

Installation:

pip install bbox-visualizer

Usage:

import bbox_visualizer as bbv

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.
