Software & data

As a result of our research and development various software have been developed.  We have decided to make these available to the research community free of charge. If you download and use the content on this page in your research, we kindly ask that you reference this website and our papers listed below.

ICC3D - A color management application

ICC3D (Interactive Color Correction in 3 Dimensions) is an application designed to help people understand and meet the challenges of color and image reproduction, especially gamut mapping.

The main application is temporarily available from here. The source code can be found here. For questions regarding the application, please contact

Colourlab Image Database: Image Quality (CID:IQ)

The Colourlab Image Database: Image Quality (CID:IQ) contain 23 pictorial images are selected as the reference images with six different distortions over 5 levels. The distortions are JPEG compression, JPEG2000 compression, Poisson noise, blurring, and two gamut mapping algorithms. CID:IQ contains the subjective scores of 17 observers. The database is available for download.

Spectral Image Database for Quality (SIDQ)

The SIDQ contains nine original 160-band hyperspectral images (MATLAB *.mat files) of scenes representing pseudo-flat surfaces of different materials (textile, wood, skin. . . ) with a spectral range between 410 and 1000nm. Five spectral distortions were designed, applied to the spectral images and subsequently compared in a psychometric experiment, in order to provide a basis for applications such as the evaluation of spectral image difference measures. The resulting 45 reproductions and raw subjective scores are also provided in the database.

The database can be downloaded here

Colon capsule endoscopy images

The data contains colon capsule endoscopy images with pathologies and normal diagnosis from different parts of the colon. There are 30 images chosen by an expert for image enhancement comparison. There are four image folder that contain implementation of two image decomposition [1, 2] techniques along with original and our proposed method. Download link.
