Optimizing parametric factors in CIELAB and CIEDE2000 color-difference formulas for 3D printed spherical objects

Forty-five spherical samples were printed using a Stratasys J750 3D color printer, and 82 pairs of 3D samples were produced to investigate the human color perception of the lightness, chroma and hue differences of 3D spherical objects, and to optimize the current CIELAB and CIEDE2000 color-difference formulas. This file contains the CIELAB values of the 45 spherical samples and the calculated colour differences as well as visual colour-difference data of 82 pairs of 3D samples. Optimizations of parametric factors in CIELAB and CIEDE2000 colour-difference formulas were performed based on the colour-difference data provided.本研究采用Stratasys J750型3D彩色打印机制备了45个球形样品，并构建82组三维样品对，用于探究人类对三维球形物体明度、彩度与色相差异的颜色感知，同时对现有CIELAB及CIEDE2000色差公式进行优化。本数据集文件包含45个球形样品的CIELAB色彩参数值，以及82组三维样品对的计算色差与目视色差数据。本研究基于本次提供的色差数据，完成了CIELAB与CIEDE2000色差公式中的参数因子优化工作。
