Paper Abstract

A method for detecting human skin and identifying the surface condition of it using the three-phase spectral matching imager (3PSMI) is proposed. The 3PSMI produces correlations pixel-wise between the spectrum of an unknown object and an orthonormal pair of known reference spectra by use of the correlation image sensor (CIS), and outputs the result as a complex image at an ordinary video frame rate, thus realizing both real-time operation and high spectral resolution. In order to apply the 3PSMI to human skin, two tasks-discrimination between skin and non-skin objects and evaluation of the degree of suntan and congestion on skin-are considered and methods of generating an orthonormal pair of reference spectra for these tasks are proposed. Experiments on these tasks are carried out on the developed 3PSMI with the reference spectra generated by the proposed methods.
