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。
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 multilluminant 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 CYNS Nmodel 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.
