Survey of target recognition technology based on spectrum imaging

The current applications of spectrum imaging recognition are summarized based on spectrum imaging recognition mechanism. Two key technologies, multi-spectral information acquirement and multi-spectral recognition, are discussed detailed. In the area of multi-spectral information acquirement, design schemes of typical multi-spectral imaging sensors are enumerated, and the advantages and shortcomings of which are compared. In the area of recognition algorithm, based on spectrum characteristics of target and decoy, the problem selecting clustering recognition character in single spectrum dimension, sequence spectrum dimension and space spectrum dimension are discussed respectively, and principles of some recognition algorithms are presented.
