The relationship between spatial color mixing with color and radiation similarity in digital camouflage study

Abstract

With the development of optical detection technology, the camouflage design in the visible light band has been unable to meet the requirements of the visible light/infrared dual-band digital camouflage detection. The digital camouflage in the human eye vision system involves factors such as the color, shape and texture of the target and background, of which color dominates. And because spatial color mixing is one of the main features of digital camouflage, it is also a key method to improve the camouflage effect. In this paper, a quantitative spatial color mixing coefficient (SCMC) method is proposed to characterize the degree of color mixing of spatial colors. The relationship between spatial color mixing coefficient and color similarity in the visible light range and the relationship between spatial color mixing coefficient and radiation similarity in the infrared range are analyzed. The relationship provides theoretical support for the design and deployment of military equipment on the battlefield. The results show that in the visible light band, the spatial color mixing coefficient can better represent the spatial color mixing degree of digital camouflage, and has a specific relationship with color similarity. In the infrared band, the spatial color mixing coefficient cannot well represent the spatial color mixing degree of digital camouflage, but it can predict its relationship with radiation similarity.
