    import numpy as np
  3. Use the detectionUsingCascades function that we wrote in Exercise 5.02, Eye Detection Using Cascades, as the starting point and modify it to incorporate the second cascade classifier as well.
  4. Revise the arguments of the function since we will be providing the paths of both cascade classifiers now:
    def detectionUsingCascades(imageFile, cascadeFile1, \
                               cascadeFile2):
  5. Load the image and create a copy of it:
        image = cv2.imread(imageFile)
