Computing the motions of several moving objects in image sequences involves simultaneous motion analysis and segmentation. This task can become complicated when image motion changes significantly between frames, as with camera vibrations. Such vibrations make tracking in longer sequences harder, as temporal motion constancy cannot be assumed. The problem(More)
Image mosaicing is commonly used to increase the visual field of view by pasting together many images or video frames. Existing mosaicing methods are based on projecting all images onto a pre-determined single manifold: a plane is commonly used for a camera translating sideways, a cylinder is used for a panning camera, and a sphere is used for a camera(More)
OBJECTIVES This study examined the effects of long-term delivery of cardiac contractility modulation (CCM) electric signals on left ventricular (LV) function and global, cellular, and molecular remodeling in dogs with chronic heart failure (HF). BACKGROUND Acute studies in dogs with experimentally induced HF showed that CCM signals applied to the failing(More)
1 I n t r o d u c t i o n Motion analysis, such as optical flow [7], is often performed on the smallest possible regions, both in the temporal domain and in the spatial domain. Small regions, however, carry little motion information, and such motion computation is therefore very inaccurate. Analysis of multiple moving objects based on optical flow.[1](More)
A method for computing the 3D camera motion (the egomotion) in a static scene is described, where initially a detected 2D motion between two frames is used to align corresponding image regions. We prove that such a 2D registration removes all effects of camera rotation, even for those image regions that remain misaligned. The resulting residual parallax(More)
AIMS To analyze long-term efficacy and survival in patients with chronic heart failure treated with cardiac contractility modulation. METHODS 81 patients implanted with a CCM device between 2004 and 2012 were included in this retrospective analysis. Changes in NYHA class, ejection fraction (EF), Minnesota Living with Heart Failure Questionnaire, NT-proBNP(More)
BACKGROUND In dogs with heart failure (HF), chronic therapy with cardiac contractility modulation (CCM) electrical signals delivered to left ventricular (LV) muscle during the absolute refractory period improves LV function. This study examined the effects of CCM therapy on the expression of calcium (Ca(2+))-binding proteins (CBPs) in dogs with HF. (More)
Video mosaicing is commonly used to increase the e ective visual eld of view. Existing mosaicingmethods are based on image alignment, and are e ective only in very limited cases. To overcome most restrictions, mosaicing is presented in this paper as a process of collecting strips. Strips which are perpendicular to the optical ow are cut out of the images,(More)
