HyAB k-means for color quantization
HyAB k-means for color quantization Color quantization in CIELAB space, visualized. The input is converted to CIELAB space and a special “HyAB” distance formula is used when clustering. This in theory should result in better image quality. I’ve been obsessing over color quantization algorithms lately, and when I learned that an image conversion app called Composite did its so-called pixel mapping step in CIELAB space, I instantly thought of the “HyAB” color distance formula I’d seen in the FLI
