I use PIL this library, use OpenCV library also can
From PIL import Image ("Demo.jpg")
Img_array=img.load ()

Then you can read the pixel value by img_array[x,y].
In addition img.size view the picture size, or you can set the RGB pixel value by img_array[x,y]= (11,22,33)


In general this kind of operation uses Python's numpy this library is more convenient

Import Cv2
Import NumPy as NP ("Demo.jpg")

Then you can read the pixel value by img_array[x,y].
