back on my project of creating images from data. I think I've finally cracked how to create nice repeating patterns
Here's another one. It's so interesting how the same process can look different depending on the file type
I was going to finish this project in time for @alpaca last year but didn't. I promise to exhibit this soon! I need to work out how this looks on bigger file sizes, and maybe even mixing in existing images.

Looks like some lossy file types don't have very obvious repeating patterns. This is the qoi file format (literally means Quite OK Image). I think I need to make these images have larger resolution so the data doesn't fill up so quickly.
I'll also one day document my process but not right now.

@hellocatfood Have you ever looked into self-similarity matrices? I've been mildly obsessed with them for visualising arbitrary data in a 2D image.

Basically you just take every data point and compare it with every other data point using some kind of useful distance metric. In this example you can kind of see the repetition of the blank lines + the repetition of the final stanza.

@boggo I have no idea what those are so I'm gonna say nope.

@boggo snap! I see. In the process I'm using the data is derived from audio so not sure how I could bring that into it. Thanks still!

@hellocatfood they always look something like this.

@hellocatfood They are actually widely used in audio! The main reason people use them actually is analysing structure of audio signals and music.

@hellocatfood i really expected that to be a magic eye image!

jxr is still one of my favourite image file formats to work with. I still need to read the file spec and work out what a "vanilla" image header looks like.

@hellocatfood woa, I hadn't heard of it, looks super fun to corrupt : O

@hellocatfood Love to hear what that sounds like in audacity.

@oin sounds kinda interesting. I'll share a clip once I've generated enough data

As suggested by @oin I imported the jxr image into audacity (U-Law, default endianness). The image is only 256x256 but it's overstuffed with data (i.e. past its actual resolution) so the file size is around 300kb and means I can have much longer audio.
Enjoy(?)

@nnenov tbh I don't know what the file format is actually used for, I just like messing with it ha! imagemagick can generate it, but not gimp

@hellocatfood @oin sounds super cool, kinda like FM synths, i wonder if thats in any way related to jpg sinewave malarkey
