Dithering part two – golden ratio sequence, blue noise and highpass-and-remap

Posted on October 30, 2016 by

In previous part of the mini-series I covered dithering definition and how dithering changes error characteristics of simple 1D quantization and functions. In this part I will try to look at what blue noise is, but first wanted to have a … Continue reading →
