Revisiting Yliluoma’s ordered dither algorithm
Summary
Revisiting Yliluoma’s ordered dithering algorithm, focusing on the Yliluoma-2 approach and its EMA variants (EMA-Sweep, EMA-Exact, EMA-Constant). The article explains a geometric interpretation for candidate selection, discusses how the mixing factor t is computed, and compares performance to Knoll’s algorithm with practical code sketches and results. It also provides guidance on color distance measures, threshold matrices, and references for further reading.
