In this post we will be creating a Python script that will apply a sketch effect to an existing image, to do this we will be using the Python Imaging Library also known as PIL enabling us to image processing capabilities.
See the sample of Python code below where we utilise the PIL library to apply a sketch effect to an image and then save it. We start by opening the image and then converting it to grayscale. Using the ‘ImageFilter’ module we then apply a contour effect to our image.
from PIL import Image, ImageFilter
img = Image.open('image.jpg')
img = img.convert('L')
img_sketch = img.filter(ImageFilter.CONTOUR)
img_sketch.save('sketch_image.jpg')
See an example image below before the effect.
See an example image below with the effect.
