Observer GLA

The following tab delimited text files provide data for observer GLA. There three files for each light field comparison: one for each change condition (change light field, change shape, change both).

Each file has a header row that indicates the contents of each column. From left to right, the columns contain the index for the reference light field (1=Grove, 2=Kitchen/Galileo); the index for the reference shape (1=Blob, 2=Pepper); index for the match light field; index for the match shape; reference specular value; reference diffuse value; specular values of the two matches; the mean specular component match; standard error of the specular match; the diffuse component values of the two matches; the mean diffuse component match; and the standard error of the diffuse component matches.

The matches can also be viewed with the Matlab script ShowMatches.m which is in the same archive as the match images.
