摘要
针对Cellular Yule-Nielsen Spectral Neugebauer(CYNSN)模型的逆向非线性Gauss-Seidel迭代算法进行了研究,提出采用多光源下XYZ方式降维,达到加速逆向CYNSN模型,并以3色和4色打印机数据进行测试。结果发现,对于3色油墨组合,采用1个光源(D50)下XYZ方式降维,以及4色油墨组合,2个光源(D50,A)下XYZ降维的逆向CYNSN模型,在精度(多光源下色差)和计算速度上均有优势。
Abstract
For the Cellular Yule-Nielsen Spectral Neugebauer (CYNSN) model, the inverse nonlinear Gauss-Seidel iterative algorithm is studied. It is proposed to use the XYZ method of multi-illuminant dimensionality reduction to achieve the accelerated inverse CYNSN model, and use 3-ink and 4-ink printer data to test. It was found that for the 3-ink combination, the XYZ dimension reduction using one light source (D50), and the 4-ink combination, the reverse CYNSN model of XYZ dimension reduction under two light sources (D50, A), not only in accuracy (more chromatic aberration under the light source), and have advantages in calculation speed.
