While most available computer vision techniques are based on RGB, in this paper, we investigate the effect of combining RGB, depth, and thermalfacial images for pain detection and pain intensity level recognition. For this purpose, we extract energies released by facial pixels using a spatiotemporal filter. Experiments on a group of 12 elderly people applying the multimodal approach show that the proposed method successfully detects pain and recognizes between three intensity levels in 82\% of the analyzed frames improving more than 6\% over RGB only analysis in similar conditions.", optnote="HuPBA;MILAB", optnote="exported from refbase (http://refbase.cvc.uab.es/show.php?record=2654), last updated on Thu, 27 Apr 2023 13:19:08 +0200", doi="10.1109/CVPRW.2015.7301341", file=":http://refbase.cvc.uab.es/files/INB2015.pdf:PDF" }
