Converting Image to Sketch with Python

 Image to Sketch

import cv2

image = cv2.imread(r"D:\image.jpg")

grey_img = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

invert = cv2.bitwise_not(grey_img)

blur = cv2.GaussianBlur(invert, (31, 91), 20)

invert_blur = cv2.bitwise_not(blur)

sketch = cv2.divide(grey_img, invert_blur, scale=290.0)

cv2.imwrite("my_sketch.png", sketch)
