6. Object Tracking

Activity 6.01: Implementing Autofocus Using Object Tracking

Solution:

1. Create a new Jupyter Notebook called Activity6.01.ipynb. We will be writing our code in this.
2. First, import the modules we will need:

   # Import modules
   import cv2
   import numpy as np
   import dlib

3. Next, create a VideoCapture object and check whether it opened successfully or not:

   Note

   The video can be downloaded from https://packt.live/2NHXwpp. Before proceeding, ensure that you can change the path to the video (highlighted) based on where the video is saved in your system.

   # Create a VideoCapture Object
   video = cv2.VideoCapture("../data/soccer2.mp4")
   # Check if video opened successfully
   if video.isOpened() == False:
       print("Could not open video!")

4. Next, capture the first frame of the video and check whether we are able to read the frame successfully or not:

   # Read first frame
   ret, frame = video.read()
   # Check if frame read successfully
   if...
