A key for current and future developments in Quality of Experience resides in a rich and internationally recognized database of content of different sorts, and to share such a database with the scientific community at large. The QUALINET Database platform takes the necessary steps to make them accessible to all researchers:

Currently, the QUALINET database comprises 122 multimedia databases, based on literature/Internet search and input from Qualinet partner laboratories. They're mostly image (~52) or video datasets (~68), with (~57) or w/o subjective quality rating, special content, e.g. 3D (~23), FV, eyetracking (~21), audio, audiovisual (~8), HDR, and other modalities.
The documentation of the QUALINET databases can be found on the corresponding Wiki page. For an overview, please consult the white paper on QUALINET databases (PDF) and please reference it as follows:
