Paper Abstract

The present paper proposes a method for recoding and rendering of art paintings using only spectral reflectance data of the object surfaces. A multiband camera system with six spectral channels of fixed wavelength bands is used for spectral imaging. No range finder is used for measuring the surface shape. We show that it is possible to render realistic images of the object for different directions of illumination, without using the 3D shape data. First, a method for estimating spectral reflectance for body reflection component of a rough surface is described. Next a method is proposed for practical image rendering. The method is based on interpolation among the images reproduced in the known illumination directions. The color signal for an arbitrary illumination direction is estimated from the color signals observed for three illumination directions. As a result, the image of an art painting object illuminated from any direction is rendered using the reflectance data obtained for three illumination directions. We present algorithms for estimating surface-spectral reflectances of an object and rendering the image for any lighting conditions. An experiment using an oil painting is executed for demonstrating the feasability of the proposed method.
