Recognition of material types using spectral image

A new method of recognition of material types is described. To materialize this idea, this paper proposes a simple color reflection model based on a dichromatic reflection model which classifies colored opaque objects into three categories: “metallic”, “matte nonmetallic” and “glossy nonmetallic”. In addition processing of a spectral image for indoor object recognition is described. An experimental image acquisition system with 2D scanning of a spectrometer is able to generate 2D spectral images, like a multi-band image. As applications of the spectral images, a spectral image is used to recognise material types, and the validity of this method is shown by experiments
