7. Object Detection and Face Recognition

Activity 7.01: Object Detection in a Video Using MobileNet SSD

Solution:

1. Firstly, open an untitled Jupyter Notebook and name the file Activity7.01.
2. We will start by importing all the required libraries for this activity:

   import cv2
   import numpy as np
   import matplotlib.pyplot as plt

3. The pre-trained model can detect a list of object classes. Let's define those classes:

   categories = {0:'background', 1:'aeroplane', 2:'bicycle', \
                 3:'bird', 4:'boat', 5:'bottle', \
                 6:'bus', 7:'car', 8:'cat', 9:'chair', \
                 10:'cow', 11: 'diningtable', 12: 'dog', \
    ...
