Revisiting Yliluoma's Ordered Dither Algorithm for Better Color Images

Revisiting Yliluoma's ordered dither algorithm

I explore Joel Yliluoma's 2011 ordered dithering method, explaining its mechanics and introducing simplified variants. By comparing these approaches against Thomas Knoll's state-of-the-art algorithm used in Adobe Photoshop, I demonstrate how specific color difference formulas can produce superior results without complex calculations.

"There's a common belief that you need complex color difference calculations for high quality dithering. I think this is mistaken."
