Databases and software

We have collected here the spectral datasets and spectral images to be used in research purposes.

Also the toolbox for Matlab can be downloaded from these pages.

Please use reference "University of Eastern Finland, Spectral Color Research Group, http://www.uef.fi/web/spectral/-spectral-database" when you use the databases from these pages, or please refer to the publication when it is mentioned.

Spectral image data

We are currently putting more efford to publish well documented spectral image data.
Table below shows our current highlights.

Name Range Spacing Image width x height x resolution Spectrals Size
Nordic sawn timbers 300-2500 nm 5 nm 200 mm x 80 mm x 250 um ~ 44 million 550 GiB

 

Please, also check our non-imaged spectral data and Matlab toolbox which are open for usage.
