OpenCV with Python in 4 Hours

Notes and code used in my Python and OpenCV course

Course Outline (with timestamps)

1. Installing the necessary packages

Besides installing OpenCV, we cover the installation of the following packages:

caer is a powerful utilities package with tons of useful helper functions for most Computer Vision tasks

$ pip install caer

canaro is a Python package solely for Deep Learning models built in Keras

$ pip install canaro
