OpenCV: Computer Vision Projects with Python

Creating modules

We should continue to maintain good separation between application-specific code and reusable code. Let's make new modules for tracking classes and their helpers.

A file called trackers.py should be created in the same directory as cameo.py (and, equivalently, in the parent directory of cascades). Let's put the following import statements at the start of trackers.py:

import cv2
import rects
import utils

Alongside trackers.py and cameo.py, let's make another file called rects.py containing the following import statement:

import cv2

Our face tracker and a definition of a face will go in trackers.py, while various helpers will go in rects.py and our preexisting utils.py file.
