Abstract

Subject of study. The features of color discrimination by the human visual system and hyperspectral technology were considered. Aim. A quantitative analysis was performed of the color discrimination capabilities of the human visual system compared with those of hyperspectral technology. Method. The research method was based on the statistical synthesis of a three-channel detector of colored spatial objects, where the spectral characteristics of the channels were similar to those inherent in the human eye. The generalized signal-to-noise ratios obtained when detecting colored objects by hyperspectral and three-channel detectors were compared while considering only the spectral (color) differences between the object and background in the absence of any energy contrast between them. The conditions for the correct transformation of the obtained results into the conditions for the observation of colored objects by a person were determined. Main results. We demonstrated that the signal-to-noise ratio ensured by a hyperspectral detector could exceed the corresponding ratio of a three-channel detector that was structurally similar to the three-component system of color-sensitive human eye receptors by a factor of 2–400. Practical significance. The obtained results could be advantageous for camouflage or, conversely, improving the recognition of colored spatial objects observed by a person or technical device.
