I am trying to design a cloth that, from the point of view of a camera, is very difficult to compress with JPG, resulting in big-size files (or leading to low image quality if file size is fixed).
It must work even if the cloth is far away from the camera, or rotated (let's say the scale can vary from 1x to 10x).
Noise is quite good (hard to compress), but it becomes grey when looking from far, becoming easy to compress. A good pattern would be kind of fractal, looking similar at all scales.
Foliage is better (leaves, tiny branches, small branches, big branches), but it uses too few colors.
Here is a first try:
I am sure there are more optimum patterns.
Maybe hexagon or triangle tessellations would perform better.
JPG uses the Y′ Cb Cr color space, I think Cb Cr can be generated in a similar way, but I guess it's better to not use uniformly the full scope of Y' (brightness) since camera will saturate the bright or dark areas (lighting is never perfect).
QUESTION: What is the optimum cloth pattern for this problem?
