A real-time object detection algorithm by using multiple cameras is proposed. The information fusion is based on homographic transformation of the foreground information from multiple cameras to a reference image. Unlike the most recent algorithms which transmit and project foreground bitmap images, we approximate the contour of each foreground region with(More)
BACKGROUND AND PURPOSE The quality of after-hour emergency care of patients with acute ischemic stroke is debatable. We therefore, sought to analyze the performance measures, quality of care and clinical outcomes in these patients admitted during off-hours. METHODS Our study included 4493 patients from a selected cohort of patients admitted to the(More)
The presence of foam influences the accuracy of satellite-derived water-leaving radiance. A model has been developed to estimate the augmented reflectance ratio (A(λ, U)) due to differences in the fraction of whitecap coverage (w) on the ocean surface. A(λ, U) can be calculated from the product of w and ρ(λ, U), where ρ(λ, U) is the augmented ratio of the(More)
