Abstract
Spectral imaging technique has attracted attention in the machine vision field to enhance measurement and inspection systems. This paper describes color analysis techniques using an imaging spectrograph for acquiring multispectral image in real-time. Two analysis cases are reported: one is the result of analyzing the relationship between skin color and the pigment by 2 kinds of multiple regression analysis, another is the result of analyzing the tone of the color of a coated surface with an undulating form using a power spectrum with shading compensation.
