YOLO thinks with 58% confidence that the Cat is a Bear 
[{'image': '/home/pi/Desktop/2020-12-29_17-11-12.953773.jpg',
  'result': ['bear: 0.5804 -> loc: 1325 : 598 : 420 : 722'],
  'timing': '[INFO] YOLO took 30.452949 seconds'}]

During 2020 I learned how to do Computer Vision amongst many other things.  I deployed a web site with Gunicorn, Flask, and Nginx, having built the server from parts. Here is a list of other articles and videos I made for sharing and giving back.
