This is neat, but the nuts and bolts are actually not that complicated. It's just a small computer running OpenCV and applying a Canny filter to the image. It's a great application for the technology, but the underlying technology is pretty old. I've used Canny filters in computer vision projects a number of times. If you want to replicate this on your own computer, the following Python code will perform a live Canny filter from your webcam:

import cv2

def canny_webcam():
cap = cv2.VideoCapture(0)

while True:
ret, frame = cap.read()
frame = cv2.GaussianBlur(frame, (7, 7), 2)
frame = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

edge = cv2.Canny(frame, 20, 50)

cv2.imshow('Canny Edge', edge)

if cv2.waitKey(20) == ord('q'):
break

canny_webcam()
