Part 1: Install Dependencies for Raspberry Pi Facial Recognition In this step, we will install OpenCV, face_recognition, imutils, and temporarily modify our swapfile to prepare our Raspberry Pi for machine learning and facial recognition. OpenCV is an open source software library for processing real...
Many of these libraries can be installed in the terminal using pip install. For example: pip install imutils The cv2 library, which is the work horse for image manipulation in this project was actually the most difficult to get working. I thinkthis tutorialwas best for getting it working on...
OnLines 2-7we import our required packages. Notably, we need OpenCV andimutils. To install OpenCV, be sure to follow one of my installation guides onthis page. You can install or upgradeimutilsvery easily via pip: $ pip install --upgrade imutils If you are using Python virtual environments ...
$ pip install imutils Next, we’ll define our extract_color_histogram function: def extract_color_histogram(image, bins=(8, 8, 8)): # extract a 3D color histogram from the HSV color space using # the supplied number of `bins` per channel hsv = cv2.cvtColor(image, cv2.COLOR_BGR2...
