Color Correction for Uniform Illumination using Multispectral Relighting

By ?????????


Capturing an object in non-uniform illuminationwas one of the problem in designing illuminationsystem. In this paper, we suggest the color correctionmethod to uniform illumination without using auniform white board. The method requires scenes incertain non-uniform illumination and commonuniform illumination. Using non-uniform illuminationwith a color filter or additional illumination,recovered spectral reflectance is obtained under nonuniform condition. The spectral reflectance isconverted to a relit scene by spectral relighting whichrelit based on wavelength, and then the relit scene iscompared with the uniform scene for color correction.By the comparison, the non-uniform scene iscorrected to uniform illuminated scene, andcomparing two scenes shows that the color correctionis conducted well. With the result, the suggestedmethod will reduce difficulty of designing illuminationsystem.This research is supported by Ministry of Culture,Sports and Tourism (MCST) and Korea CreativeContent Agency (KOCCA) in the Culture Technology(CT) Research & Development Program 2016
