import scipy.ndimage
import cv2
img = "elon.jpg"


def rgb2gray(rgb):
return np.dot(rgb[..., :3], [0.2989, 0.5870, .1140])



def dodge(front,back):
    final_sketch = front*255/(255-back)
    final_sketch[final_sketch >255] =255
    final_sketch[back == 255] =255

    return final_sketch.astype('uint8')


ss = imageio.imread(img)
gray = rgb2gray(ss)
i = 255-gray
blur = scipy.ndimage.filters.gaussian_filter(i, sigma=13)
r = dodge(blur, gray)
cv2.imwrite('elon.png',r)
