BACKGROUND Timely provision of an ankle-foot orthosis (AFO) orthotist customized for individuals early after stroke can be problematic. OBJECTIVE To evaluate the efficacy of a therapist-made AFO (SWIFT Cast) for walking recovery. METHODS This was a randomized controlled, observer-blind trial. Participants (n = 105) were recruited 3 to 42 days poststroke. All received conventional physical t...

Moving object detection is an important task in real-time video surveillance. However, in real scenario, moving cast shadows associated with moving objects may also be detected, making moving cast shadow detection a challenge for video surveillance. In this paper, we propose an adaptive shadow detection method based on the cast shadow model. The method combines ratio edge and ratio brightness, ...

Computer Aided Detection (CAD) established its role in medical imaging as second reader aimed to boost the diagnostic accuracy of human interpreter. As the diagnostic performance of CAD systems improves and more imaging modalities are covered, CAD steps forward to fill new, more demanding positions in medical practice. In this paper we investigate how the introduction of CAD for emergency diagn...
