An improved spectral reflectance estimation method is developed to transform raw camera
RGB responses to spectral reflectance. The novelty of our method is to apply a local …

In this work, a methodology is introduced to use ordinary digital RGB cameras for the
purpose of spectral and colorimetric color reproduction. First, it is attempted to recover the …

A novel spectral reflectance reconstruction method based on kernel partial least square
(KPLS) regression is proposed. The proposed method integrates the partial least square …

A color appearance model (CAM) is an advanced colorimetric tool used to predict color
appearance under a wide variety of viewing conditions. A chromatic adaptation transform …

In this paper, a technique named step by step progressive method is devised for recovery of
spectral data from the corresponding colorimetric information. The method consists of …

Three numerical methods are presented for finding the smoothest reflectance curve
associated with a given triplet of tristimulus values. The methods differ in how “smooth” is …

A procedure for recovering spectral reflectance from CIE tristimulus values is presented
using a modified pseudo-inverse method. Unlike previous spectral recovery methods, this …

In this work, we address the problem of spectral reflectance recovery from both CIEXYZ and
RGB values by means of a machine learning approach within the fuzzy logic framework …

To improve the estimation accuracy of spectral reflectance from the given trichromatic value,
a new two-step k-nearest neighbors locally weighted linear regression method is proposed …

We use the mobile phone camera as a new spectral imaging device to obtain raw responses
of samples for spectral estimation and propose an improved sequential adaptive weighted …
