title: How to search not same images but similar images by pyautogui
body: <p>I use pyautogui to search an image on Desktop window for click automation.</p>
  
  <blockquote>
    <p>pyautogui.locateOnScreen(image)</p>
  </blockquote>
  
  <p>If the image is captured on the same screen as screenshot, it can be matched. However, if the image is a bit different, it cannot. e.g. captured as the low resolution image.
  Can I set some likelihood in pyautogui or use other library?</p>
