One popular approach for multi-camera detection of pedestrians or other objects of interest in surveillance scenes is to perform background subtraction and project the resulting foreground mask images to a common scene plane using homographies. As the complexity of the scene increases, it is unavoidable that so called “ghost” detections should occur. These(More)
The sensitivity of non-isotopic in situ hybridization (NISH), particularly on formalin-fixed, paraffin-embedded (FFPE) clinical tissues, has been the subject of controversy. Generally, NISH has been regarded as being less sensitive than radiolabelled procedures, although some reports have contradicted this. Accordingly, tissues from mice which were(More)
We have used a probe against the adenovirus genome to study cultured epithelial cells specifically infected with various types of adenovirus and Graham 293 cells, which contain few copy numbers of a fraction of the adenovirus genome. We have also examined lung tissue obtained from three cases of acute adenovirus pneumonia, two cases of adenovirus pneumonia(More)
In an attempt to identify more clearly the origin of cells in human basal cell carcinoma xenografts in mice, paraffin and frozen sections were subjected to in situ DNA hybridization with biotin labelled human and murine DNA probes. Human skin and mouse skin sections were used as controls. As expected, the implanted epithelium reacted with the human DNA(More)
The present work presents a new method for activity extraction and reporting from video based on the aggregation of fuzzy relations. Trajectory clustering is first employed mainly to discover the points of entry and exit of mobiles appearing in the scene. In a second step, proximity relations between resulting clusters of detected mobiles and contextual(More)
In this article, we describe two pregnancies in the same patient after pancreatic-renal transplantation. Severe, labile hypertension necessitated delivery at 35 weeks during the patient's first pregnancy and at 30 weeks (associated with renal graft obstruction) during her second pregnancy. Women with insulin-dependent diabetes mellitus who undergo(More)
16 This paper presents a video surveillance framework that robustly and effi17 ciently detects abandoned objects in surveillance scenes. The framework is 18 based on a novel threat assessment algorithm which combines the concept 19 of ownership with automatic understanding of social relations in order to 20 infer abandonment of objects. Implementation is(More)
A number of multi-camera solutions exist for tracking objects of interest in surveillance scenes. Generally, the approach follows the idea of either early fusion (where all cameras are used to make a decision about detection and tracking) or late fusion (where objects are detected and tracked in individual cameras independently, and then the results(More)
