WebJun 30, 2014 · Here we define the image_stats function, which accepts a single argument: the image that we want to compute statistics on. We make the assumption that the image is already in the L*a*b* color space, prior to calling cv2.split on Line 49 to break our image into its respective channels.

The “mean” should be the mean value of the raw pixels in your training set, for each color channel separately. The “std” should be the standard deviation of the raw pixels in your training set, for each color channel separately.
