import cv2

img = cv2.imread("C:\\pworkspace\\mypy\\pythontech\\funnyscripts\\elon.png")

## Image to Gray Image

gray_image = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

## Gray Image to Inverted Gray Image

inverted_gray_image = 255-gray_image

## Blurring The Inverted Gray Image

blurred_inverted_gray_image = cv2.GaussianBlur(inverted_gray_image, (19,19),0)

## Inverting the blurred image

inverted_blurred_image = 255-blurred_inverted_gray_image

### Preparing Photo sketching

sketck = cv2.divide(gray_image, inverted_blurred_image,scale= 256.0)

cv2.imshow("Original Image",img)

cv2.imshow("Pencil Sketch", sketck)
