问题描述

我想使用PIL库从大图像中查找子图像.我还想知道在哪里找到坐标?

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

推荐答案

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)

这对我来说很好且有效.

This works fine and in efficient way for me.
