CONTROL-BASED INVERSION FOR ESTIMATING BIOLOGICAL PARAMETER VECTOR FOR BIOPHYSICS MODEL FROM DIFFUSED REFLECTANCE DATA

摘要

The present invention relates to a system and a method for estimating biophysics model using reflectance data obtained from a reflectance-based spectroscopic measuring system. The method uses a half-experience biophysics model to describe skin features and reflectance spectrums, and reduces dimensionality of estimated and measured reflectance spectrums using base vectors for computing efficiency. Mixing of algorithms is adopted to generate an initial set of clean parameters using a repeated control-based scheme compared with parameters calculated from spectrums having an estimated error between parameters derived from a next order measured spectroscopy. The errors are processed to generate an initial set of next small delta to parameters. The process is repeated until an error between estimated virtual biological parameters and measured virtual parameters is reduced to zero or becomes a pre-defined threshold or less.;COPYRIGHT KIPO 2014
