Jan 19, 2018 · This method is based on an imaging system consisting of many narrowband light sources and transmission filters attached to a camera. These ...

Abstract. The spectrum behavior of a typical fluorescent object is regulated by its reflectance, absorption and emission spectra. It was shown that two high ...

An algorithm is then presented for estimating both radiance factors from two sets of spectral images of the camera outputs, captured under two light sources.

where Fu is the image taken in an unknown light source and Fc is the transformed image as if taken under a canonical illuminant, while Du,c is the spectral ...

The present paper proposes a solution method for the illuminant estimation problem in the case of composite illuminants involving both spiky and continuous ...

We show that three hyperspectral images under wideband and independent illuminants are both necessary and sufficient, and successfully develop a convex ...
