Abstract

Noh is a famous traditional Japanese dramatic art. The restoration of ancient Noh masks is an important aspect of the preservation of cultural heritage. In this paper, we developed a technique based on Retinex algorithm and it can be applied to restore the color of 3D objects such as the Noh mask. The Retinex algorithm simulates the ability of human eye and can adjust the color of the 2D image. To apply the Retinex algorithm on the 3D surface, the shape of the object is taken into account. The original color of the target points can be got by reference to the color of the surrounding points sampled according to a uniform route. The effectiveness of this technique is demonstrated by the implementation results. This technique can be used to infer the color of other 3D objects also.
