Resynthesizer python lib

https://github.com/61315/resynthesizer wrapped into python library

Resynthesizer is a very old (2000 year) open-source equivalent to Adobe Photoshop's "Content-Aware Fill" feature

Installation:

pip install resynthesizer

Usage:

from resynthesizer import resynthesize
from PIL import Image

source = Image.open('source.jpg')
# mask must have black background, white foreground
mask = Image.open('mask.png')
result = resynthesize(source, mask)
result.save('result.jpg')

You can adjust resynthesizer's params if you want:

from resynthesizer import TImageSynthParameters

# same as defaults
params = TImageSynthParameters()
params.isMakeSeamlesslyTileableHorizontally = 1
params.isMakeSeamlesslyTileableVertically = 1
params.matchContextType = 1
params.mapWeight = 0.5
params.sensitivityToOutliers = 0.117
params.patchSize = 30
params.maxProbeCount = 200

# or get defaults
from resynthesizer import getDefaultParams
params = getDefaultParams()

...

result = resynthesize(source, mask, parameters=params)

try

In console:

python package/resynthesizer/resynthesizer.py image.png mask.png [out.png]

Or in Gradio UI:

Install Gradio 3 demo requirements and run:

python -m venv venv
. venv/bin/activate
pip install gradio==3.41.2 pillow
python ./demo.py

Windows:

python -m venv venv
venv\Script\activate
pip install gradio==3.41.2 pillow
pip install msvc-runtime setuptools
# you also need to have installed https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#latest-microsoft-visual-c-redistributable-version
python ./demo.py

resynthesizer.so build

1. git clone https://github.com/61315/resynthesizer

2. install gcc, make

3. Modify Makefile (added -fPIC, use gcc instead of clag, remove all examples):

4. Link:

gcc -shared -o lib.so build/resynthesizer/*.o

5. For .dll I've used x86_64-w64-mingw32-gcc from sudo apt-get install gcc-mingw-w64 instead of gcc. It shows strange worse result on my virtual machine, I don't know why. They are the same if I build in VM using clang, or if I build it on Linux

6. For Max OS .dylib was built by the author: 61315/resynthesizer#6 (comment)
