Shi's Re-processed Version of the Gehler
Color Constancy Dataset of 568 Images
This dataset is based on work done by Dr. Lilong
Shi at Simon Fraser University with Dr. Brian Funt.
It involves processing the original RAW format images provided by Gehler et al. to
generate a new set of high quality linear images. New ground truth
illumination measurements are also provided for these images.

Manually Labeled Color Constancy Datasets

May 15, 2012
A total of 1,913 images are included in the 3 data sets. We manually
labeled each of these images with its
the 3D stages and its indoor/outdoor classification. Following Nedovic et al., the 15 typical
3D stages sky+bkg+grd, bkg+grd, sky+grd,
grd, nodepth, grd+Tbkg(LR),
Tbkg(LR), Tbkg(RL), tbl+Prs+bkg, 1sd+wall(LR),
1sd+wall(RL), corner, corridor, and prs+bkg
are used. There are separate files in both Matlab
(.mat) and plain text (.txt) formats containing the file name from the
original data set, a 0/1 flag indicating indoor/outdoor, and a
numerical stage value.
The image labeling provided here has been used in a paper entitled,
“Evaluating Combinational Illumination-Estimation Methods on Real-World
Images,” by Bing Li, Weihua
Xiong, Weiming Hu, Brian Funt.
This paper is still under review (as of May 2012) and is not yet
publically available. If you use the label sets we provide here, please

Mismatching Hue Circle Transition Wavelengths
data for Table II of “Logvinenko, A.D., Funt,
B., and Godau, C., "Metamer
Mismatching," IEEE Trans. on Image Processing, Vol. 23, No.
1, pp. 34-43, Jan. 2014” is available here.
The data files consist of 20 rows of the 5 transition wavelengths
defining a reflectance spectrum. Note that transitions T1, ..., T5 are
given in order. In some rows the wavelengths are increasing, some
decreasing. For the increasing case, the reflectance is zero for all
wavelengths less than T1, one from T1 to T2, zero from T2 to T3, and so
on. For the decreasing case, the reflectance is zero for all
wavelengths greater than T1, one from T1 down to T2, zero from T2 down
to T3, and so forth.
