Webcv2.getTickFrequency function returns the frequency of clock-cycles, or the number of clock-cycles per second. So to find the time of execution in seconds, you can do following: e1 = cv2.getTickCount() # your code execution e2 = cv2.getTickCount() time = (e2 - e1)/ cv2.getTickFrequency() We will demonstrate with following example.
