PixelSort CLI
A CImg based implementation of pixel sorting--a technique popularized by visual artist Kim Asendorf whose github can be found here.
Really dig how simple the idea is + cool the results are:
- Apply a binary threshold to create pixel segments along rows or columns (this helps retain features of the original image)
- Sort the segments by some measurable metric (in this case, I used luminance--could also use hue, saturation, etc.)
The program displays the sorted, greyscale, and original images before exiting.
Example
./pixelsort -i input/moss.jpg -o output/moss_v.jpg -l 30 -u 210 -v true
Usage
Options to sort pixels by column or row, tweak the threshold values(0-255), and save the pic.
-i (input image: default moss picture included in input/)
-o (output image: default no save)
-l (lower threshold: default 30)
-u (upper threshold: default 210)
-v (vertical: default true)
Building on Linux
Compile using g++ and included makefile. i.e.make
Notes:
- Requires ImageMagick for imports
