What is Pixel Sorting?
Have a look at this post or /r/pixelsorting
Dependencies
Should work in both Python 2 and 3, but Python 3 is recommended.
Usage
From the command line:
pip install pixelsort
python3 -m pixelsort %PathToImage% [options]
Tip: To replicate Kim Asendorf's original processing script, first sort vertically and then horizontally in threshold
(default) mode:
python3 -m pixelsort %PathToImage% -a 90
python3 -m pixelsort %PathToSortedImage%
As a package:
>>> from pixelsort import pixelsort
>>> from PIL import Image
>>> a = Image.open("examples/image.jpg")
>>> a
<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=576x324 at 0x7F8F6A2AC208>
>>> pixelsort(a)
<PIL.Image.Image image mode=RGBA size=576x324 at 0x7F8F66AA57B8>
Parameters:
Parameter | Flag | Description |
---|---|---|
Interval function | -i | Controls how the intervals used for sorting are defined. See below for more details and examples. Threshold by default. |
Output path | -o | Path of output file. Uses the current time for the file name by default. |
Randomness | -r | What percentage of intervals not to sort. 0 by default. |
Threshold (lower) | -t | How dark must a pixel be to be considered as a 'border' for sorting? Takes values from 0-1. 0.25 by default. Used in edges and threshold modes. |
Threshold (upper) | -u | How bright must a pixel be to be considered as a 'border' for sorting? Takes values from 0-1. 0.8 by default. Used in threshold mode. |
Char. length | -c | Characteristic length for the random width generator. Used in mode random and waves . |
Angle | -a | Angle at which you're pixel sorting in degrees. 0 (horizontal) by default. |
External interval file | -f | Image used to define intervals. Must be black and white. |
Sorting function | -s | Sorting function to use for sorting the pixels. Lightness by default. |
Mask | -m | Image used for masking parts of the image. |
Logging level | -l | Level of logging statements made visible. Choices include DEBUG , INFO , WARNING , ERROR , and CRITICAL . WARNING by default. |
Interval Functions
Interval function | Description |
---|---|
random | Randomly generate intervals. Distribution of widths is linear by default. Interval widths can be scaled using char_length . |
edges | Performs an edge detection, which is used to define intervals. Tweak threshold with threshold . |
threshold | Intervals defined by lightness thresholds; only pixels with a lightness between the upper and lower thresholds are sorted. |
waves | Intervals are waves of nearly uniform widths. Control width of waves with char_length . |
file | Intervals taken from another specified input image. Must be black and white, and the same size as the input image. |
file-edges | Intevals defined by performing edge detection on the file specified by -f . Must be the same size as the input image. |
none | Sort whole rows, only stopping at image borders. |
Sorting Functions
Sorting function | Description |
---|---|
lightness | Sort by the lightness of a pixel according to a HSL representation. |
hue | Sort by the hue of a pixel according to a HSL representation. |
saturation | Sort by the saturation of a pixel according to a HSL representation. |
intensity | Sort by the intensity of a pixel, i.e. the sum of all the RGB values. |
minimum | Sort on the minimum RGB value of a pixel (either the R, G or B). |
Examples
python3 -m pixelsort examples/image.jpg -i random -c 20
python3 -m pixelsort examples/image.jpg -i edges -t .5
file
: Intervals taken from image specified with-f
. Must be black and white.
python3 -m pixelsort examples/image.jpg -i file -f examples/intervals.png
(generated with elementary-ca)
mask
: Mask taken from image specified with-m
. Must be black and white.
python3 -m pixelsort examples/image.jpg -i random -c 20 -m examples/mask.png
Todo
- Allow defining different intervals for different channels.
