from PIL import Image, ImageFilter

class MyGaussianBlur(ImageFilter.Filter):
  name = "GaussianBlur"

  def __init__(self, radius=2, bounds=None):
    self.radius = radius
    self.bounds = bounds

  def filter(self, image):
    if self.bounds:
      clips = image.crop(self.bounds).gaussian_blur(self.radius)
      image.paste(clips, self.bounds)
      return image
    else:
      return image.gaussian_blur(self.radius)

bounds = (150, 130, 280, 230)
image = Image.open('source.jpg')
image = image.filter(MyGaussianBlur(radius=29, bounds=bounds))
image.show()
