Template matching image: [python] import cv2 import numpy as np img = cv2.imread("simpsons.jpg") gray_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) template = cv2.imread("barts_face.jpg", cv2.IMREAD_GRAYSCALE) w, h = template.shape[::-1] result = cv2.matchTemplate(gray_img, template, cv2.TM_CCOEFF_NORMED) loc = np.where(result >= 0.4) for pt in zip(*loc[::-1]): cv2.rectangle(img, pt, (pt[0] + w, pt[1] + h), (0, 255, 0), 3) cv2.imshow("img", img) cv2.waitKey(0) cv2.destroyAllWindows() […]
