Detailed Description

DIN99d color difference metric with optional power transformation.

Computes the Euclidean distance between two colors in DIN99d color space. Optionally applies a power transformation for improved perceptual uniformity.

Template Parameters

ColorType1,ColorType2

Any color type convertible to colors::DIN99d.

Parameters

use_power_transform	Whether to apply power transformation (default: true).
power	Power value for transformation (default: 0.74).
scale	Scale factor after transformation (default: 1.28).
