Pixsort: An artistic pixel sorting program

==========================================

The purpose of this script is to perform a “pixel sorting”

effect that purposefully perturbs an image in order to pretend that it

was damaged.

A simple sorting algorithm is used at present: after sharpening the

images, edges are detected and pixels are being sorted from the edge

with highest intensity (for every row of the image). This is not

the most sophisticated algorithm yet but it already yields some

interesting results.

Usage

-----

Use `-f` to indicate the fraction of all rows of the image that should

be sorted. To glitch all rows, use `1.0`:

    $ ./pixsort.py -f 1.0 Images/Lena_small.jpg

If not specified differently with `-o`, the new image will be the

basename of the old image with plus `_sorted`. For this example,

the file name will be `Lena_small_sorted.jpg`. See below for the

results.

Examples

--------

  

  Lena (original)

  

  Lena (sorted)

Requirements

------------

- `PIL`

Future extensions

-----------------

- Permit sorting of columns as well

- Handle RGB images

- More algorithms for glitching an image
