- 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.
original dataset is described in Peter Gehler and
Carsten Rother and
Andrew Blake and Tom Minka and Toby Sharp, "Bayesian
Color Constancy Revisited", Proceedings of the IEEE Computer
Society Conference on Computer Vision and Pattern Recognition, 2008.
The original Gehler dataset is available from here.
Peter Gehler for making his images publically
available and for permission to post our new versions of them. The new SFU
Shi version is available for download here. Note that
the black level offset needs to be subtracted from the original images. A Matlab template for loading the images and removing the
offset is available here.

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), grd+Tbkg(RL), 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 contact one of the authors

- Metamer Mismatching Hue Circle Transition Wavelengths
Full precision data for Table II of Logvinenko, A.D., Funt, B., and Godau, C., "Metamer Mismatching," IEEE Trans. on Image Processing,

(***Soon***). 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.
