“Track and Accumulate” (T&A) is an alternative astronomical image capture method where exposures are combined during imaging by aligning on a reference star. The benefit is an increased dynamic range, thus allowing both bright and dim objects to be captured in the same image. The main limitation is that correlated noise from the frames will form squiggles on the combined image as the result of...
We present an interactive framework for rapid 3D reconstruction of objects from sets of photographs. Our framework implements advanced 2D image-based modeling techniques that accurately compute geometries of digital photorealistic 3D models in a rapid and robust method. It is implemented in an application tool to assist users to perform feature detection, matching and meshing. Our system demonstrates...
An active camera, i.e., pan-tilt-zoom camera, can monitor a large area and the detail of a target. Therefore, it is popularly used in recent studies related to intelligent surveillance systems. A novel dual-PTZ-camera surveillance system called ldquoEagle-Eyerdquo is proposed in this paper. The view of the system is designed to imitate an eagles eye. That is, the system can keep monitoring the whole...
