# DeepCreamPy
*Decensoring Hentai with Deep Neural Networks. Formerly named DeepMindBreak.*

This project applies an implementation of [Image Inpainting for Irregular Holes Using Partial Convolutions](https://arxiv.org/abs/1804.07723) to the problem of hentai decensorship. Using a deep fully convolutional neural network, DeepCreamPy can replace censored artwork in hentai with plausible reconstructions. The user needs to only specify the censored regions.

# What's New?
- Decensoring images of ANY size
- Decensoring censors of ANY shape (e.g. bunch of black lines, pink hearts, etc.)
- Higher quality decensors
- Support for mosaic decensors
- User interface (still a WIP and not very usable)

# Installation

## Download Prebuilt Binaries
You can download the latest release [here](https://github.com/deeppomf/DeepCreamPy/releases/latest) or find all previous releases [here](https://github.com/deeppomf/DeepCreamPy/releases).
Binary only available for Windows 64-bit.

## Run Code Yourself
If you want to run the code yourself, you can clone this repo and download the model from https://drive.google.com/open?id=1byrmn6wp0r27lSXcT9MC4j-RQ2R04P1Z. Unzip the file into the /models/ folder.

### Dependencies (for running the code yourself)
- Python 3
- TensorFlow 1.10
- Keras 2.2.4
- Pillow
- h5py

No GPU required! Tested on Ubuntu 16.04 and Windows. (Tensorflow on Windows is compatible with Python 3 and not Python 2.)

Tensorflow, Pillow, and h5py can all be installed by running in the command line

```
$ pip install -r requirements.txt
```

# Limitations
The decensorship is intended to work on color hentai images that have minor to moderate censorship of the penis or vagina.

It does NOT work with:
- Black and white images
- Monochrome images
- Hentai containing screentones (e.g. printed hentai)
- Real life porn
- Censorship of nipples
- Censorship of anus
- Animated gifs/videos

In particular, if a vagina or penis is completely censored out, decensoring will be ineffective.

# Usage
## I. Decensoring bar censors

For each image you want to decensor, using image editing software like Photoshop or GIMP to color the areas you want to decensor the green color (0,255,0), which is a very bright green color.

*I strongly recommend you use the pencil tool and NOT the brush tool.*

*If you aren't using the pencil tool, BE SURE TO TURN OFF ANTI-ALIASING on the tool you are using.*

I personally use the wand selection tool with anti-aliasing turned off to select the censored regions. I then expand the selections slightly, pick the color (0,255,0), and use the paint bucket tool on the selection regions.

To expand selections in Photoshop, do Selection > Modify > Expand or Contract.
To expand selections in GIMP, do Select > Grow.

Save these images in the PNG format to the "decensor_input" folder.

### A. Using the binary

Decensor the images by double-clicking on the decensor file.

### B. Running from scratch

Decensor the images by running

```
$ python decensor.py
```

Decensored images will be saved to the "decensor_output" folder. Decensoring takes a few minutes per image.

## II. Decensoring mosaic censors

As with decensoring bar censors, perform the same steps of coloring the censored regions green and putting the colored image into the "decensor_input" folder.

In addition, move the original, uncolored images into the "decensor_input_original" folder. Ensure each original image has the same names as their corresponding colored version in the "decensor_input" folder.

For example, if the original image is called "mermaid.jpg," then you want to put this image in the "decensor_input_original" folder and, after you colored the censored regions, name the colored image "mermaid.png" and move it to the "decensor_input" folder.

### A. Using the binary

Decensor the images by double-clicking on the decensor_mosaic file.

### B. Running from scratch

Decensor the images by running

```
$ python decensor.py --is_mosaic=True
```

Decensored images will be saved to the "decensor_output" folder. Decensoring takes a few minutes per image.

## III. Decensoring with the user interface

To be implemented.

# Troubleshooting
If your decensor output looks like this:

![Bad decensor](/readme_images/mermaid_face_censored_bad_decensor.png)

then the censored regions were not colored correctly.

*Make sure you have antialiasing off.*

Here are some examples of bad and good colorings:

|Image|Zoom|Comment|
|--- | --- | ---|
|![Incomplete coloring](/readme_images/mermaid_face_censored_bad_incomplete.png)|![Incomplete coloring](/readme_images/mermaid_face_censored_bad_incomplete_zoom.png)|Some censored pixels was left uncolored. Expand your selections to fully cover all censored regions.|
|![Bad edges](/readme_images/mermaid_face_censored_bad_edge.png)|![Bad edges](/readme_images/mermaid_face_censored_bad_edge_zoom.png)|Some pixels around the edges of the green regions are not pure green. This will cause the green to bleed into the decensors. Make sure anti-aliasing is off and to use a pencil tool and not a brush tool if possible.|
|![Perfect coloring!](/readme_images/mermaid_face_censored_good.png)|![Perfect coloring! The censored region is uniformly colored correctly.](/readme_images/mermaid_face_censored_good_zoom.png)|Perfect coloring!|

# To do
- Finish the user interface

Contributions are welcome! Special thanks to StartleStars for contributing code for mosaic decensorship and SoftArmpit for greatly simplifying decensoring!
