APPARATUS AND METHOD FOR JOINT REFLECTANCE AND FLUORESCENCE SPECTRA ESTIMATION

摘要

Embodiments are directed to apparatuses and methods that jointly estimate reflectance and fluorescence spectra. An example embodiment includes providing captured intensity characteristics indicative of a target, the intensity characteristics acquired by illuminating the target with different illuminants and passing light in different spectral bands via a photodetector apparatus and providing reflectance properties and fluorescent properties of the target. The example embodiment further includes concurrently adjusting the reflectance properties and fluorescence properties to reduce a quantity indicative of a combination of: a difference between the captured intensity characteristics and intensities predicted using an image formation model incorporating the reflectance properties and fluorescence properties, functions of the reflectance properties, and functions of the fluorescence properties.
