The Stack Blur filter for Pillow.
The Stack Blur Algorithm was invented by Mario Klingemann, mario@quasimondo.com and described here: http://incubator.quasimondo.com/processing/fast_blur_deluxe.php
This original C++ RGBA (32 bit color) multi-threaded version by Victor Laskin (victor.laskin@gmail.com) could be found here: http://vitiy.info/stackblur-algorithm-multi-threaded-blur-for-cpp
The python implementation is porting from C++ multi-threaded version. And wrap the implementation as a filter for pillow.
Blur the image with radius 10.
from stackblur import StackBlur
from PIL import Image
im = Image.open('img.png')
im = im.filter(StackBlur(10))
im.save('blurred_img.png')Install via setup tools:
./setup.py install
Install via PIP:
pip install -e git://github.com/JonesChi/pillow-stackblur.git#egg=pillow-stackblur
Please remember to install pillow before using this library.
