Addiction à l'alcool, objet concret et régulation des éprouvés internes [PDF]
, 2004 International audienceClinical work with alcoholics led us to examine intra-psychic tensions that existed prior to alcoholism and to foresee using them as a strategy for controlling—external, specific, and illusory—their “indescribable” internal feelings.

Heart Rate Measurement Based on 3D Central Difference Convolution with Attention Mechanism
Sensors, 2022 Remote photoplethysmography (rPPG) is a video-based non-contact heart rate measurement technology. It is a fact that most existing rPPG methods fail to deal with the spatiotemporal features of the video, which is significant for the extraction of the ...

Video pulse rate variability analysis in stationary and motion conditions [PDF]
, 2018 Background: In the last few years, some studies have measured heart rate (HR) or heart rate variability (HRV) parameters using a video camera. This technique focuses on the measurement of the small changes in skin colour caused by blood perfusion.

On Using rPPG Signals for DeepFake Detection: A Cautionary Note
, 2023 An experimental analysis is proposed concerning the use of physiological signals, specifically remote Photoplethysmography (rPPG), as a potential means for detecting Deepfakes (DF). The study investigates the effects of different variables, such as video compression and face swap quality, on rPPG information extracted from both original and forged ...
