The color spectrum recognition method using statistical methods to extract the features of the spectra is fast, insensitive to noise and especially suitable for industrial environment. Because the color spectra are directly discriminated, there is no metamerism. And so the color spectral recognition may be widely used for on-line quality control and machine vision. We aim to study how many color differences can be discriminated by the spectrum recognition method in general condition. A color spectrum recognition system is introduced in this paper. In our experiments, two sheets of white paper with 1. 1 NBS unit of color difference between them were used as targets and the Averaged Learning Subspace Method (ALSM) was used to calculate subspace classificatory. Using this subspace classificatory, the system can recognize the two targets in real time.
