Implicit monitoring of the user perception by using physiological signals has been attracting much attention with the noticeable development of sensors and processing tools. This database is collected to investigate the perceptual experience of tone-mapped HDR videos by using physiological signals.
This database includes physiological signals (EEG, GSR, respiration, plethysmography, and skin temperature), video sequences, and questionnaire results. Details of the data can be found in our paper that is mentioned below.
Physiological signals were recorded while subjects are watching videos. The signals are in .bdf file format, and named as follows:
(subject ID)_(name of corresponding video)_(type of corresponding video)
Two types of videos, namely, 'ldr' and 'tmd' are included in this database. Both types of videos are in a standard dynamic range (or low dynamic range) of luminance, but videos of 'tmd' type were tone-mapped from high dynamic range while videos of 'ldr' type were not. There are four contents of videos, hall, objects, sky, and window.
Results of the questionnaire are named with subject ID and the number of question (e.g., Q1), and aligned in alphabetical order of the name of corresponding video, i.e.,
hall_1080p_ldr, hall_1080p_tmd, objects_1080p_ldr, objects_1080p_tmd, ...
