This SOBER-DRUNK DATA BASE was created at Electronics Laboratory, Physics Department, University of Patras, Greece (Started September 2012 - Completed April 2013) by Georgia Koukiou and Vassilis Anastassopoulos (gkoukiou@upatras.gr , vassilis@upatras.gr)

Every body from the scientific community and the national and international authorities worldwide can use this database testing and publishing experimental results, provided that she/he will refer to relevant publications of the creators of the database.

The infrared images used in this work were acquired by means of the Thermo Vision Micron/A10 Model infrared camera (18 mm, f/1.6) of the FLIR Company. Its operating wavelengths range from 7.5 to 13.0 microns. The obtained information is in the thermal infrared where the maximum of the Wien curve lies (9.5 microns for 300 Kelvin black body – Human skin behavior). In this experimental procedure forty-one people were involved, 31 males and 10 females. Each person consumed four glasses of red wine, 120 ml each (13% vol.), in one hour - time period (a total of 480 ml of wine i.e. 62.4 ml of alcohol). The first acquisition of 50 frames for each specific person was obtained just before starting alcohol consumption, whereas the second acquisition of 50 frames 30 minutes after drinking the fourth glass of wine. In each acquisition, a sequence of 50 frames was obtained for each person with a sampling period of 100 msec between the frames. The resolution of the infrared images is 128x160 pixels.

A MATLAB program is provided for reading each separate file.
