Hands-On Machine Learning for Cybersecurity

Code

In the first step, we will write a machine learning system using image-processing techniques that will be able to read letters from images.

We import the relevant packages; cv2 is the respective OpenCV package, as shown in the following code:

import osimport os.pathimport cv2import globimport imutils

We read in the images, but we will output the respective letters in the images:

CAPTCHA_IMAGES_PATH = "input_captcha_images"LETTER_IMAGES_PATH = "output_letter_images"

We list all of the CAPTCHA images that are present in the input folder and loop over all of the images:

captcha_images = glob.glob(os.path.join(CAPTCHA_IMAGES_PATH, "*")) counts = {} for (x, captcha_images) in enumerate(captcha_image_files): print("[INFO] processing image ...
