Ho do computers see images? – Opencv with Python
We’re going to understand today how do computers see images. I’m going to explain that using python with opencv.
Here below the python code used in the video tutorial:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
import cv2 import numpy as np # Black square img = np.zeros((10, 10, 3), np.uint8) img[0, 0] = (255, 0, 0) # Blue img[0, 1] = (0, 255, 0) # Green img[0, 2] = (0, 0, 255) # Red img[1, 0] = (0, 150, 150) # Yellow (green + red) img[1, 1] = (150, 0, 180) # Magenta (blue + red) # Resizing the image x100 to see each pixel big img = cv2.resize(img, (1000, 1000), interpolation=cv2.INTER_AREA) # Show the image cv2.imshow("Image", img) cv2.waitKey(0) |
