Pleasing color harmonies appeals to our sense of beauty. Our study is an attempt to explore such aesthetic aspect of color by scientific approach using mathematics and computer. Digital images of fine art, especially images of paintings, are significant resources for computational analysis of color aesthetics. We have developed a software system, specially designed for multilateral color analys...

Spatial terms in the world’s languages appear to reflect both universal conceptual tendencies and linguistic convention. A similarly mixed picture in the case of color naming has been accounted for in terms of near-optimal partitions of color space. Here, we demonstrate that this account generalizes to spatial terms. We show that the spatial terms of 9 diverse languages near-optimally partition...

– A new technique of color face recognition is proposed. First processing stage consists of an optimum color conversion from the 3D RGB space into a 2D selected feature space using the old Karhunen-Loève transform (KLT). The resulted 2D color space is defined by the two color components (called C1 and C2), corresponding to the two largest eigenvalues of the RGB pixel covariance matrix. The seco...
