Generalization of Video-Based Heart Rate Estimation Methods To Low Illumination and Elevated Heart Rates [PDF]

open access: yesarXiv
Heart rate is a physiological signal that provides information about an individual's health and affective state. Remote photoplethysmography (rPPG) allows the estimation of this signal from video recordings of a person's face. Classical rPPG methods make use of signal processing techniques, while recent rPPG methods utilize deep learning networks ...

Deep-learning models improve on community-level diagnosis for common congenital heart disease lesions [PDF]

open access: yesarXiv, 2018
Prenatal diagnosis of tetralogy of Fallot (TOF) and hypoplastic left heart syndrome (HLHS), two serious congenital heart defects, improves outcomes and can in some cases facilitate in utero interventions. In practice, however, the fetal diagnosis rate for these lesions is only 30-50 percent in community settings. Improving fetal diagnosis of congenital
