How to find subimage using the PIL library?

Question

I want to find the sub-image from large image using PIL library. I also want to know the coordinates where it is found ?

Answer 1

import cv2
import numpy as np
image = cv2.imread("Large.png")
template = cv2.imread("small.png")
result = cv2.matchTemplate(image,template,cv2.TM_CCOEFF_NORMED)
print np.unravel_index(result.argmax(),result.shape)

This works fine and in efficient way for me.
