Naturalness assessment can be utilized as a criterion to evaluate performance of preferred color corrections and to compare naturalness of images reproduced by displays. This paper presents a new model to assess naturalness based on three dimensional color space. Experimental results indicate that the proposed model outperforms three previous models proposed for the naturalness assessment.
