Histogram Matching:

    #Histogram Equalization
    img[:, :, 0] = cv2.equalizeHist(img[:, :, 0])
    img[:, :, 1] = cv2.equalizeHist(img[:, :, 1])
    img[:, :, 2] = cv2.equalizeHist(img[:, :, 2])

    #Image Resizing
    img = cv2.resize(img, (img_width, img_height), interpolation = cv2.INTER_CUBIC)

    return img
