UCID - Uncompressed Colour Image Database
The aim of the Uncompressed Colour Image Database (UCID - pronounced "use-it") is to provide a
benchmark dataset for image retrieval where all images were captured and are available in
uncompressed form. The current version of the database (v2) has over 1300 images together with a
ground truth (predefined query images with corresponding model images that should be retrieved).
It is envisaged that the dataset is used for the evaluation of image retrieval techniques that operate
directly in the compressed domain (so-called 4th criterion algorithms) and to investigate the effect
image compression has on the performance of CBIR methods.
