We present a method for reconstruction of the visual hull (VH) of an object in real-time from multiple video streams. A state of the art polyhedral reconstruction algorithm is accelerated by implementing it for parallel execution on a multi-core graphics processor (GPU). The time taken to reconstruct the VH is measured for both the accelerated and non-accelerated implementations of the algorithm,...
Latency in a communication system can result in confusing a conversation through loss of causality as people exchange verbal and non-verbal nuances. This paper compares true end-to-end latencies across an immersive virtual environment and a video conference link using the same approach to measure both. Our approach is to measure end-to-end latency through filming the movements of a participant and...
We present a prospective 10-16 year clinical and pedobarographic evaluation of a modification to the Kates et al forefoot arthroplasty. Thirty-five patients were initially recruited into the study. All patients suffered with rheumatoid arthritis and had severe pain in the forefoot. Prior to surgery, patients underwent both clinical and pedobarographic evaluation. Of the original 35 patients, 12 had...
Freiberg's disease, often described as a form of osteochondritis juvenalis, usually affects the second and occasionally the third metatarsal heads. It is most common in adolescent females and is associated with secondary degenerative change. The case presented is a 60-year-old female who developed Freiberg's disease in both the second and third metatarsal heads of the same foot. Whilst the coexistence...
