WitrynaThe gamut mapping algorithm provides among the best results in color constancy experiments [3]. Finlayson et al. [12] improve the gamut mapping algorithm by restricting the transformations to be plau- sible, meaning that only illuminants are allowed which correspond to existing illuminants.

WitrynaFigure 1: Illustration of the basic idea of gamut mapping color constancy. Once the set of possible maps has been computed, an important second stage of the algorithm is to choose a solution from the feasible set. The original method was to choose the mapping which maximized the volume of the mapped set.

WitrynaThe IPT color appearance model excels at providing a formulation for hue where a constant hue value equals a constant perceived hue independent of the values of lightness and chroma (which is the general ideal for any color appearance model, but hard to achieve). It is therefore well-suited for gamut mapping implementations. ICtCp Witryna6 gru 2016 · In this paper, we propose a green (G)-channel restoration for a red–white–blue (RWB) color filter array (CFA) image sensor using the dual sampling technique. By using white (W) pixels instead of G pixels, the RWB CFA provides high-sensitivity imaging and an improved signal-to-noise ratio compared to the Bayer CFA. …
