Blurry JPG from super-compressing a geometric image.
An experimental image compression: pixel blocks converted to gradients between darkest and lightest pixels in block.
After getting very excited about Voronoi Diagrams and this post, I took a break from PHP to make what I think is essentially a custom image-compression algorithm. I’ve applied it to Van Gogh’s famous painting “Starry Night” at varying levels. The program, written in Processing, essentially looks at a pixel’s neighbors and if the colors are similar enough, it sets the neighbor’s value to the tested pixel. The above image is a allows for a difference of as much as 250 (very high compression/low similarity) and steps down in increments of 25 down to 25.
