| Research Abstract |
Recovery of spectral reflectances of objects being imaged through the use of image data is important to reproduce color images under various illuminations. Although the Wiener estimation is usually used for the recovery, but the recovery performance of this estimation depends on the autocorrelation matrix of the spectral reflectances and the noise present in an image acquisition system. The goal of the present study is to show that the Wiener estimation that uses the noise variance estimated by the previous proposal and the autocorrelation matrix that uses the features of the spectral reflectances recovered by the previous method is very effective to greatly improve the performance.
