请问mobileface_enhancement.py第36行的calcHist传入的图片是bug还是故意这么写的？ #15

mobileface_enhancement.py第36行的calcHist函数：hist = cv2.calcHist(img_gray, [0], None, [256], [0, 256])的img_gray没有用中括号，这样计算的是img_gray第一个维度的直方图而不是整个图片的直方图，计算整个图片的直方图应该是hist = cv2.calcHist([img_gray], [0], None, [256], [0, 256])，请问这里是写错了，还是算法就是要计算第一个维度的直方图？谢谢！

@guoguangchao The effect of img_gray is similar or even better than [img_gray]. You can try them freely and choose which method to use according to the actual situation.

我试过了，确实不加中括号的效果更明显，谢谢
