Cartoonizer in Python

 A Python script that converts a normal image into a cartoonified one ..

The code ..

My image 

You can use any image you want ..

import cv2  # pip install opencv-python

class Cartoonizer:
   def __init__(self):
      pass

   def render(self, img_rgb):
      img_rgb = cv2.imread(img_rgb)
      img_rgb = cv2.resize(img_rgb, (1366,768))
      numDownSamples = 2  # number of downscaling steps
      numBilateralFilters = 50 # number of bilateral filtering steps

      # -- STEP 1 --

      # downsample image using Gaussian pyramid
      img_color = img_rgb
      for _ in range(numDownSamples):
         img_color = cv2.pyrDown(img_color)

      #cv2.imshow("downcolor",img_color)
      #cv2.waitKey(0)
      # repeatedly apply small bilateral filter instead of applying
      # one large filter
      for _ in range(numBilateralFilters):
         img_color = cv2.bilateralFilter(img_color, 9, 9, 7)

      #cv2.imshow("bilateral filter",img_color)
      #cv2.waitKey(0)
      # upsample image to original size
      for _ in range(numDownSamples):
         img_color = cv2.pyrUp(img_color)
      #cv2.imshow("upscaling",img_color)
      #cv2.waitKey(0)

      # -- STEPS 2 and 3 --
      # convert to grayscale and apply median blur
      img_gray = cv2.cvtColor(img_rgb, cv2.COLOR_RGB2GRAY)
      img_blur = cv2.medianBlur(img_gray, 3)
      #cv2.imshow("grayscale+median blur",img_color)
      #cv2.waitKey(0)

      # -- STEP 4 --
      # detect and enhance edges
      img_edge = cv2.adaptiveThreshold(img_blur, 255,
                              cv2.ADAPTIVE_THRESH_MEAN_C,
                              cv2.THRESH_BINARY, 9, 2)
      #cv2.imshow("edge",img_edge)
      #cv2.waitKey(0)

      # -- STEP 5 --
      # convert back to color so that it can be bit-ANDed with color image
      (x,y,z) = img_color.shape
      img_edge = cv2.resize(img_edge,(y,x))
      img_edge = cv2.cvtColor(img_edge, cv2.COLOR_GRAY2RGB)
      #cv2.imwrite("edge.png",img_edge)
      return cv2.bitwise_and(img_color, img_edge)

tmp_canvas = Cartoonizer()

file_name = "av.jpg" #File_name will come here
res = tmp_canvas.render(file_name)

#cv2.imwrite("Cartoon version.jpg", res)     # if you want to save it
cv2.imshow("Cartoon version", res)
cv2.waitKey(0)
cv2.destroyAllWindows()

And the output ...

I know it is not that good ...

... But anyways :)
