Abstract：According to the spectral features of polluted-gases infrared spectra, a mixed multi-branch spectral discriminator is proposed. Experimental results indicate that the spectral discriminator not only has simple structure and high veracity for classification and recognition, but also has remarkable flexibility and stability. So it is a high-efficiency discriminator for real-time identified infrared spectra of polluted gases.
