連続性を考慮した三刺激値からの分光反射率の推定

抄録

We propose a method for estimating spectral reflectance from tristimulus values observed. We use the fact that the real spectral reflectance is continuous. We formulate the estimation problem as a minimization of spectral reflectance difference between neighboring wavelengths, and show the analytic solution. Experimental results show that the proposed method improves the estimation accuracy compared with the previous method.
