Accurate measurements of athletes' stride parameters, such as stride/step length, stride/step frequency, stance times and foot contact times are important to coaching support and biomechanics research in sprinting. Existing stride parameter monitoring approaches are either expensive, or insufficiently accurate, or not suitable for supporting daily training sessions. This paper investigates the use...
Humans are poor, if not incapable, at localizing sound underwater due to significant reduction in Inter-aural Temporal Differences (ITD) and Inter-aural Intensity Differences (IID) caused by reduced impedance mismatch and the higher sound speed in water. An improvement in sound localization underwater will significantly enhance divers safety, the way divers perceive and appreciate the underwater environments...
Stride-related parameters of sprinters, such as split times (i.e. which is speed-related), foot contact times, stance times, stride/step length, and stride/step frequency, etc. are important factors which affect athletes' performances. Traditionally, this information is captured by biomechanics researchers and coaches using optical-based systems. However, these systems are expensive, time consuming...
Sensing the presence and state of people is of paramount importance in assistive living environments. In this paper we utilise a set of fixed, calibrated cameras to model the bodies of people directly in three dimensions. An adaptive foreground segmentation algorithm is run per camera, providing evidence to be collected in 3D body blobs. A particle filter tracker allows monitoring the modelled bodies...
