Detection of respiratory activity in newborn infants using a noncontact vision-based monitor.

Objective: To examine the effectiveness of a noncontact vision-based infrared respiratory monitor (IRM) in the detection of authentic respiratory motion in newborn infants.

Study Design: Observational study in a neonatal intensive care unit.

Methods: Eligible infants lay supine with torso exposed under the IRM's infrared depth-map camera and torso images were recorded at 30 frames/s.

Automated control of oxygen titration in preterm infants on non-invasive respiratory support.

Objective: To evaluate the performance of a rapidly responsive adaptive algorithm (VDL1.1) for automated oxygen control in preterm infants with respiratory insufficiency.

Design: Interventional cross-over study of a 24-hour period of automated oxygen control compared with aggregated data from two flanking periods of manual control (12 hours each).

Automatic Torso Detection in Images of Preterm Infants.

Imaging systems have applications in patient respiratory monitoring but with limited application in neonatal intensive care units (NICU). In this paper we propose an algorithm to automatically detect the torso in an image of a preterm infant during non-invasive respiratory monitoring. The algorithm uses normalised cut to segment each image into clusters, followed by two fuzzy inference systems to detect the nappy and torso.

Eye-screen distance monitoring for computer use.

The extended period many people now spend looking at computer screens is thought to affect eyesight over the long term. In this paper we are concerned with developing and initial evaluation of a wireless camera-based tracking system providing quantitative assessment of computer screen interaction. The system utilizes a stereo camera system and wireless XBee based infrared markers and enables unobtrusive monitoring.

A single camera stereographic imaging system for tracking upper limb motions.

A single camera stereographic imaging system was designed, built and tested for the intended application of tracking upper limb motion. The system consisted of a camera, quad-mirror system and image acquisition and processing software. This paper describes the design methods used and the testing of the system.
