Contactless vital-sign monitoring can improve comfort and hygiene in long-term, sleep, home, and clinical monitoring, but robust estimation of heart rate (HR), respiratory rate (RR), and oxygen saturation (SpO2) remains a coupled sensing and algorithmic problem. This paper summarizes our research line on remote photopl...

This work presents a correction model for a multispectral method for 2.5D shape measurement, based on the Shape from Focus principle. Using a monocular imaging system of a filter wheel camera, depth information is derived from the respective focus position. Both lateral (2D) and axial (z-axis) measurement accuracy must...
