The development of non-contact techniques for monitoring human vital signs has significant
potential to improve patient care in diverse settings. By facilitating easier and more …

This paper presents an approach to assess the perfusion of visible human tissue from RGB
video files. We propose metrics derived from remote photoplethysmography (rPPG) signals …

Flap loss through limited perfusion remains a major complication in reconstructive surgery.
Continuous monitoring of perfusion will facilitate early detection of insufficient perfusion …

Hyperspectral imaging (HSI) is a new emerging modality useful for the noncontact
assessment of free flap perfusion. This measurement technique relies on the optical …

Existing challenges in surgical education (See one, do one, teach one) as well as the
COVID-19 pandemic make it necessary to develop new ways for surgical training. Therefore …

This paper presents a model-based approach to measure the vital signs from RGB video
files focusing on the heart rate. We use the plane-orthogonal-to-skin (POS) remote …

Significance: Hyperspectral and multispectral imaging (HMSI) in medical applications
provides information about the physiology, morphology, and composition of tissues and …

Analyzing periodic video sequences is a key topic in applications such as automatic
production systems, remote sensing, medical applications, or physical training. An example …

Imaging techniques in gastrointestinal surgery are white light endoscopy, and increasingly
fluorescence dye imaging (FI)(ICG). Endoluminal ultrasound (US), optical coherence …

The modified Allen test (MAT) is a widely used tool to examine the perfusion capacities of
the arteries (ulnar or radial) of the hand. In clinical practice, MAT is utilized to ensure that in …
