Modified Pyblur

Modify function of Pyblur, also add StochasticMotionBlur

Installation

From pip: pip install git+https://github.com/PD-Mera/pyblur.git

Or alternatively git clone this repo and run locally

git clone https://github.com/PD-Mera/pyblur.git
pip install -e pyblur

Usage

Random Blur

Randomly applies one of the supported blur types, with a randomized bandwidth/strengh.

from PIL import Image
from pyblur import RandomizedBlur

img = Image.open("test.jpg").convert("RGB")
blurred = RandomizedBlur(img)
blurred.save("test.jpg")

or you can modify DEFAULT_BLUR_FUNCTIONS to randomize with your own config

from PIL import Image
from pyblur import RandomizedBlur, DEFAULT_BLUR_FUNCTIONS

# print(DEFAULT_BLUR_FUNCTIONS) # Using if you want to see more config
blurFunctions = DEFAULT_BLUR_FUNCTIONS.copy()
blurFunctions["StochasticMotionBlur"]["intensity_min"] = 0.2

img = Image.open("test.jpg").convert("RGB")
blurred = RandomizedBlur(img, blurFunctions)
blurred.save("test.jpg")
