Last active September 22, 2022 02:23
This is sample code for template matching tutorial using OpenCV on Raspberry Pi
import cv2
import numpy as np
img = cv2.imread("Cover.jpg")
gray_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
template = cv2.imread("Raspberry Pi.jpg", 0)
w, h = template.shape[::-1]
count = 0
res = cv2.matchTemplate(gray_img, template, cv2.TM_CCORR_NORMED )
#methods = ['cv.TM_CCOEFF', 'cv.TM_CCOEFF_NORMED', 'cv.TM_CCORR','cv.TM_CCORR_NORMED', 'cv.TM_SQDIFF', 'cv.TM_SQDIFF_NORMED']
