更快的图像识别？

Question

CastImage = pag.locateCenterOnScreen('Cast.png', region=(426, 579, 643, 676))
PullImage = pag.locateCenterOnScreen('pull.png', region=(426, 579, 643, 676)) 
stopper = pag.locateCenterOnScreen('stopper.png')
ensure = pag.locateCenterOnScreen('ensure.png', region=(154, 88,  624, 132))

我希望这部分代码更快，因为在屏幕上搜索照片会耗费太多时间（我甚至指定了要搜索这些照片的区域，但没有帮助）。也许我应该去别的图书馆？如何更快地在屏幕上定位图像

以下是我的完整代码：

import pyautogui as pag
import time


def cast():
    flag = True
    while flag:
        CastImage = pag.locateCenterOnScreen('Cast.png', region=(426, 579, 643, 676))
        print('searching for cast image')
        if CastImage is not None:
            time.sleep(0.2)
            click = pag.click(CastImage)
            print('clicking cast image')
            flag = False


def pull():
    flag = True
    while flag:
        PullImage = pag.locateCenterOnScreen('pull.png', region=(426, 579, 643, 676))
        print('searching for pull image')
        if PullImage is not None:
            time.sleep(0.2)
            click1 = pag.click(PullImage)
            print('clicking pull image')
            flag = False


def strength():
    flag = True
    stopper = pag.locateCenterOnScreen('stopper.png')
    ensure = pag.locateCenterOnScreen('ensure.png', region=(154, 88,  624, 132)) # ensures that this is right window(with game)
    while flag:
        print('Searching for strengthBAR')
        strengthgreen = pag.locateOnScreen('strength.png', region=(355, 304, 774, 528))
        if strengthgreen is None and ensure is not None:
            clickPull = pag.mouseDown(534, 634) # FIXED VALUE
            print('PULLING')
        if stopper is not None:
            flag = False
            print('Stopping strength function')


while True:
    cast()
    pull()
    strength()
