Middlebury Color Datasets
- Registered Color Checker images
We provide registered views of two color calibration targets, X-Rite's
and 140-patch Digital
ColorChecker SG. Each pattern was photographed:
- with 35 different camera models, 24 of which support both RAW and JPEG, while 11 support only JPEG;
- with fixed "Tungsten" white balance (wb1); for a subset of cameras also with "auto" white balance (wb2);
- under two fixed lighting conditions: using 3200K Tungsten (i1) and 4800K Daylight (i2) photo flood light bulbs;
- with 4 different exposures: stops -2 (e1), -1 (e2), 0 (e3), and +1 (e4).

- Registered RAW-JPEG pairs of natural scenes We provide 85
registered RAW/JPG pairs of natural scenes taken with 12 different
camera models; both "scaled" (linearly down-sampled) versions
attenuating noise and compression effects, and "cut" versions
composited from patches of the original images.

- Registered JPEG images of planar surfaces
We provide registered images of planar surfaces taken with 5 different
camera models, from different viewpoints, under different lighting,
and with different white balance and exposure. The views were
registered using Chuck Stewart's GDB-ICP software after
correcting for radial lens distortion.
