Illuminant Estimation By Deep Learning [PDF]
, 2018 Computational color constancy refers to the problem of estimating the color of the scene illumination in a color image, followed by color correction of the image through a white balancing process so that the colors of the image will be viewed as if the ...

Revisiting and Optimising a CNN Colour Constancy Method for Multi-Illuminant Estimation [PDF]
LIM, 2021 The aim of colour constancy is to discount the effect of the scene illumination from the image colours and restore the colours of the objects as captured under a ‘white’ illuminant.

Shape estimation in natural illumination [PDF]
CVPR 2011, 2011 The traditional shape-from-shading problem, with a single light source and Lambertian reflectance, is challenging since the constraints implied by the illumination are not sufficient to specify local orientation. Photometric stereo algorithms, a variant of shape-from-shading, simplify the problem by controlling the illumination to obtain additional ...

Estimation of illumination characteristics [PDF]
IEEE Transactions on Image Processing, 2001 The description of the relation between the one-parameter subgroups of a group and the differential operators in the Lie-algebra of the group is one of the major topics in Lie-theory. We use this framework to derive a partial differential equation which describes the relation between the time-change of the spectral characteristics of the illumination ...

Differences in illumination estimation in #thedress
Journal of Vision, 2017 We investigated whether people who report different colors for #thedress do so because they have different assumptions about the illumination in #thedress scene. We introduced a spherical illumination probe (Koenderink, Pont, van Doorn, Kappers, & Todd, 2007) into the original photograph, placed in fore-, or background of the scene and—for each ...

Adaptive colour constancy algorithm using discrete wavelet transform [PDF]
, 2012 The colours of chromatically homogeneous object surfaces measured by a sensor vary with the illuminant colour used to illuminate the objects. In contrast, colour constancy enables humans to identify the true colours of the surfaces under varying ...

Video-Based Illumination Estimation [PDF]
, 2011 One possible solution to estimating the illumination for color constancy and white balance in video sequences would be to apply one of the many existing illumination-estimation algorithms independently to each video frame. However, the frames in a video are generally highly correlated, so we propose a video-based illumination-estimation algorithm that ...
