Detailed Description

CIEDE2000 (Delta E 2000) color difference metric.

Computes the perceptual color difference between two colors using the CIEDE2000 formula, the most accurate standard for perceptual color difference. Allows optional weighting factors for lightness, chroma, and hue.

While most accurate, this is also the most computationally intensive of the metrics.

Template Parameters

ColorType1,ColorType2

Any color type convertible to colors::Lab.

Parameters

K_L	Lightness weighting factor (default: 1.0).
K_C	Chroma weighting factor (default: 1.0).
K_H	Hue weighting factor (default: 1.0).
