The study worked on the spectral reflectance reconstruction method based on kernel entropy component analysis(KECA).The spectral reflectance reconstruction algorithm was constructed by principal component analysis(PCA) and kernel principal component analysis(KPCA) respectively.Then color reproduction was studied and compared with the spectral reflectance algorithm based on KECA.The results show that the spectral reconstruction algorithm based on KECA is superior to PCA and KPCA in chromaticity accuracy and spectral accuracy.The study shows that KECA is valuable for the real reproduction of the surface color of the object in practice.
