A thumbnail of each picture is shown below. To inspect individual files click on the corresponding figure. Individual images are for inspection purposes only (.jpg files are not calibrated!). To download the calibrated imagery you have to download the large .zip files and decompress them. Then you will find two directories, one with uncalibrated pictures (called pics) and another with files in matlab (.mat) format containing individual calibrated images.

Calibrated Images database: click on the dataset you want to download.
WARNING: individual files are larger than 1Gb

Overview

The urban scenery database

A thumbnail of each picture is shown below. To download the whole database (in CIE XYZ space) as a large (1.5 Gb) rar-compressed file please click here (warning: file> 1Gb). if you are interested in downloading the same database but converted to the LMS cone sensitivities using the Stockman and Sharpe (2000) 2-deg cone sensitivities in 1nm steps, please click here (warning: file >1Gb). The corresponding LMS cone sensitivities using the Smith and Pokorny (1975) cone sensitivities are here (warning: file >1Gb). Individual images below are for inspection purposes only (.jpg files are not calibrated!).
