Multimodal Intensity Pain (MIntPAIN): An RGBDT video pain database

We present the first publicly available database, ’Multimodal Intensity Pain (MIntPAIN)’ database, for RGBDT pain level recognition in sequences. We provide baseline results including 5 pain levels recognition by analyzing independent visual modalities and their fusion with deep CNN and LSTM models.

The database was captured by giving electrical muscle pain stimulation to the subjects. It has 20 subjects. Each subject exhibited two trials during data capturing session and each trial has 40 sweeps of pain stimulation. In each sweeps we captured two data: one for no pain (Label0) and the other one for pain (Label1-Label4). As a whole each trial has 80 folders from 40 sweeps (some sweeps are missing for some subjects). Each of the 80 folders in the trial folders contains three folders for RGB, Depth and thermal video frames of one stimulation. A synchronization of frames between all these modalities along with some other supporting script are provided with the database and described below.
