在下面的代码中，Im拍摄视频的每一帧并使用opencv的CLAHE函数执行直方图均衡。

import numpy as np
import matplotlib.pyplot as plt
import cv2
import imutils


#Read video
while True:
    VIDEO = cv2.VideoCapture('cellvid3.avi')
    ok, videoWidget = VIDEO.read();
    image = VIDEO.get(cv2.CAP_PROP_POS_FRAMES);    
    #Adaptive Histogram Equalization
    clahe = cv2.createCLAHE(clipLimit=6, tileGridSize= (8,8))
    cl1 = clahe.apply(image)

但是，此错误在最后一行返回（clahe.apply）
