OpenCV 4 with Python Blueprints - Second Edition

Preparing the main script

The main script will be responsible for the complete logic of the app. It will process a video stream and use an object-detection deep convolutional neural network combined with the tracking algorithm that we will prepare later in this chapter.

The algorithm is used to track objects from frame to frame. It will also be responsible for illustrating results. The script will accept arguments and have some intrinsic constants, which are defined in the following initialization steps of the script:

1. As with any other script, we start by importing all the required modules:

import argparseimport cv2import numpy as npfrom classes import CLASSES_90from sort import Sort

We will use argparse as we want our script to accept ...
