• Write "Get started"
• Create an animation gif to show how it works
• Write quick summary of poisson image editing

It would be great if user can load source or target images by drag-and-drop'ping.
Require investigation if it's feasible in tkinter.

pip install -r requirements.txt fails with the error on Max OS X.

pip install -r requirements.txt

...

        from numpy.distutils.core import setup

    ImportError: No module named numpy.distutils.core

    ----------------------------------------
    Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/3s/7v9d19q90752p8_nqzxj4cg80000gn/T/pip-build-MKi69E/pyamg

Current workaround is to install numpy independently before running pip install -r requirements.txt

pip install numpy==1.8.1

Increase test coverage!!

Make everyone's life easier by putting PyPoi to PyPI so people can use PyPoi through pip. (Repeat bold text five times as fast as you can 😛)

Overview

Executable file (one file mode) for MacOSX created by PyInstaller doesn't work well.
This issue doesn't happen in multi file mode or in Windows

Symptom

Whenever user clicks the blend button in GUI, it prints the following error message.

Action to be taken

It looks that something is wrong around math calculation (pyamg, scipy).
GUI works fine in Windows and even in Mac when multi file mode is used, and also I plan to register PyPoi to PyPI (#15), after that we don't need to use the PyInstaller anymore.
Hence, I'll leave it as it is and for v0.1.1 I'll release only multi file version for Mac OS.

Show default mask when users select examples, so that users only need to click the "Blend" button to see the result.
For example, when user selects an example, mask is loaded as well as below.

Hi,
it's a great work of your. i really appreciate.

i would like to propose the extension as functionality that allows the library to be used from python. e.g import pypoi and directly able to use the pypoi.blend(...)

for that i see the following tasks :

1. exposing the functionality.
2. documenting the function signature better that clarifies the expectations

I am putting it out if someone takes these tasks. Some functionality i have already posted in the pull request. #30
will try to implement others.

cheers,

As the title says, when I click on example 4, nothing shows up.

Make executable files for Windows and Mac OSX and upload it as a release.
User only needs to go to the release tab, download an executable and launch it to explore.

Thanks for this awesome tool!

Just wondering if it would be possible to add a rotate option, to rotate either mask or image itself

With numpy==1.16.2, the following exception occurs when blending images.

Exception in Tkinter callback
Traceback (most recent call last):
  File "/Users/besshf/anaconda3/envs/pypoi/lib/python2.7/lib-tk/Tkinter.py", line 1547, in __call__
    return self.func(*args)
  File "/Users/besshf/src/PyPoi/pypoi/gui.py", line 179, in blend
    src.flags.writeable = True
ValueError: cannot set WRITEABLE flag to True of this array

This error is reproducible by

from PIL import Image
import numpy as np

print(np.__version__)  # 1.16.2

# https://github.com/fbessho/PyPoi/raw/v0.2.1/pypoi/testimages/test1_src.png
path = 'pypoi/testimages/test1_src.png'
image = Image.open(path)

array = np.asarray(image)
array.flags.writeable = True

Add function to share blended image, for example

• Upload a result image to a hosting service and generate an URL.
• Connect with facebook, twitter

Currently, all GUI stops during calculation so user cannot know if the program is doing something or something wrong happens.
It's really confusing.

By showing progress bar during calculation, user can know program is calculating in the back.

To explain how to use this app.
Perhaps I need to upload it to youtube or somewhere else.

Blending doesn't work well when the target image has strong gradient (see the image below).

Gradient of a source image could be retained by using Gradient Mixture.
See this article in opencv.jp (Japanese) for technical details.

Is there anyway to speed up this image editing process? Such as..

• Use faster algorithm (of matrix calculation?)
• Multi-core usage
• By using approximation?
