Drag and drop as many images as you need. If you do anything with it I’d love to see it!Įdit: The script was used to make this music video. This tool does it all for you, just drag and drop all your images onto the canvas, thats all you need to do, after youve finished adding all your images, click the 'Download Sprite Sheet' button. It shouldn’t be too hard to use, details are in REAMDE.md. On the bottom left is the image with sorted intervals.Īll the images in this article were generated using a pixel sorting script I wrote in python – source here.On the bottom left is the image with the intervals filled in with random colors – each color represents a different interval.Notice that the foam – too light – and the shadows – too dark – are outside the threshold. The top right is the image with pixels outside the lightness threshold replaced with black, and the rest filled in with white.In pixel sorting, you first iterate through the image, and identify intervals of pixels that fall within a certain threshold for some value (ex: pixel intensity or hue). The intervals are defined by regions of the image that are too light or too dark – the edges of these regions define the edges of the intervals. This is an art project that allows you to create glitchy looking images through pixel sorting.
#PIXEL SORTER MAKING CODE#
Kim Asendorf’s code simply applies this technique twice: first vertically, then horizontally. It was popularized (possibly invented) by artist Kim Asendorf (processing source code here). Pixel sorting is an interesting, glitchy effect which selectively orders the pixels in the rows/columns of an image.
The rows/columns of the image are split into ‘intervals’ (more on this later).They propose using it as a technique for unsupervised classification, to be applied to images from remote sensing satellites. Neat! The earliest reference to pixel sorting I could find on the internet is this paper ( PDF) by scientists from Iraq’s Scientific Research Council. The processing script was cryptic and not very hackable, and I felt like something more lightweight was needed, so I wrote my own version in python – more info on GitHub. Pixel Sorting Introducing order in a disordered way can make for some great glitch art.
