Image matching is a cornerstone technology in many image understanding, augmented reality and recognition applications. The state-of-the-art techniques follow a feature-based approach by extracting interest points and describing them by either rotation or affine invariant descriptors. However, requiring rotation or affine invariance comes at an additional computational cost as well as inaccurate estimates...
We investigate the problem of stitching timely synchronized video streams captured by freely moving devices. Recently, it was shown that using frame-to-frame correlation can greatly enhance the efficiency and effectiveness of video stitching algorithms [19]. In this paper, we address some of the shortcomings in [19], namely the simple blending approach, causing almost a third of stitching errors and...
Mobile phones are becoming more and more ubiquitous with a large number of these devices having image/video capturing capabilities, connection capabilities and built-in rich sensory. This has encouraged the common user to capture more image/video content than ever before. However, this has created two interrelated problems: 1) while capturing some scene the user may want to get more information about...
Constructing a panoramic video out of multiple incoming live mobile video streams is a challenging problem. This problem involves multiple users live streaming the same scene from different angles, using their mobile phones, with the objective of constructing a panoramic video of the scene. The main challenge in this problem is the lack of coordination between the streaming users, resulting in too...
Background Primary health-care centers provide outpatient health care and primary preventive activities for people in general and for mothers and children in particular. Medical care aims not only to improve health status, but also to respond to patients’ needs and wishes and to ensure their satisfaction with care. The patient-clinician relationship is a central feature of primary care. Objective...
