Abstract

Accurate color classification by vector subspace method was implemented by simple optical system including computer controlled set of light-emitting diodes and a photo-receiver operating in the integration regime. The technique is capable for fast and precise classification of color distribution within two-dimensional frame with high spatial resolution. The feasibility of the proposed system is shown by a test of four metameric colors, which were correctly distinguished.
