# Decompose
[Fast Soft Color Segmentation](https://github.com/pfnet-research/FSCS) without `Residue predictor`.
[Paper PDF](https://arxiv.org/pdf/2004.08096.pdf)
## Installation
```bash
pip install git+https://github.com/setanarut/decompose
```
## Example
```python
from decompose.decomposer import decompose
from PIL import Image
img = Image.open("image.jpg")
layers = decompose(img)
for layer in layers:
print(layer)
# Decomposer mask generation...
# Decomposer processing alpha layers...
# Decomposer Done!
#
#
#
#
#
#
#
```
You can write layers as [ORA](https://docs.krita.org/en/general_concepts/file_formats/file_ora.html) file
```python
from decompose.utils import images_to_ORA
images_to_ORA(layers).save("img.ora")
```
If palette is not given as an argument, a palette is created automatically. Colors can be selected manually.
```python
manual_palette = [
(255, 255, 255),
(3, 135, 3),
(3, 193, 160),
(1, 167, 255),
(255, 243, 0),
(193, 0, 0),
(3, 0, 2),
]
layers = decompose(img, manual_palette)
```
## decomp command-line tool example
Saves layers as ORA (Open Raster) file. It can be opened with Krita. Also saves the palette.
```bash
$ decomp ~/Desktop/img.png
# Decomposer mask generation...
# Decomposer processing alpha layers...
# Decomposer Done!
# ORA saved: img.ora
# 7
# Palette saved: img_palette.png
```
## Note
The model only supports 7 colors. The same color can be repeated for less color.
