# SOM in Python for images

This is a very simple Python implementation of a

[Self-Organizing Map](http://en.wikipedia.org/wiki/Self-organizing_map)

for colors classification in a given image.

## Dependencies

* [Python 3](http://python.org/)

* [Pillow](http://pillow.readthedocs.org/en/latest/)

## Run

    python som.py input_image.png output_image.png

## Example

### Input

![Lenna](lenna.png?raw=true)

### Output

![Result](result.png?raw=true)

## Warnings

* This was hacked together in about an hour.

* Only accepts square images.

* Quite slow.

## Improvement ideas

* Parallelize.

* Better weights initialization (for a cleaner output).

* Stop after convergence.

* Writer cleaner code / split into modules.

* Support non square images.
