20120300068 | Method and System for Cooperative Diversity Visual Cognition in Wireless Video Sensor Networks - A method and system for cooperative diversity visual cognition in a wireless sensor network is disclosed. The method and system are capable of solving distributed visual cognition tasks (for example, online simultaneous reconstruction of 3D models of a large area) by using multiple video streams and exploiting cooperative diversity video sensing information while ensuring an optimal tradeoff between energy consumption and video quality of images received from said multiple video streams. | 11-29-2012 |

20100007740 | Statistical modeling and performance characterization of a real-time dual camera surveillance system - The present invention relates to a method for visually detecting and tracking an object through a space. The method chooses modules for a restricting a search function within the space to regions with a high probability of significant change, the search function operating on images supplied by a camera. The method also derives statistical models for errors, including quantifying an indexing step performed by an indexing module, and tuning system parameters. Further the method applies a likelihood model for candidate hypothesis evaluation and object parameters estimation for locating the object. | 01-14-2010 |

20090148046 | ERROR PROPOGATION AND VARIABLE-BANDWIDTH MEAN SHIFT FOR FEATURE SPACE ANALYSIS - The present invention comprises using error propagation for building feature spaces with variable uncertainty and using variable-bandwidth mean shift for the analysis of such spaces, to provide peak detection and space partitioning. The invention applies these techniques to construct and analyze Hough spaces for line and geometrical shape detection, as well as to detect objects that are represented by peaks in the Hough space. This invention can be further used for background modeling by taking into account the uncertainty of the transformed image color and uncertainty of the motion flow. Furthermore, the invention can be used to segment video data in invariant spaces, by propagating the uncertainty from the original space and using the variable-bandwidth mean shift to detect peaks. The invention can be used in a variety of applications such as medical, surveillance, monitoring, automotive, augmented reality, and inspection. | 06-11-2009 |

20090062641 | Method and system for catheter detection and tracking in a fluoroscopic image sequence - A method and system for detecting and tracking an ablation catheter tip in a fluoroscopic image sequence is disclosed. Catheter tip candidates are detected in each frame of the fluoroscopic image sequence using marginal space learning. The detected catheter tip candidates are then tracked over all the frames of the fluoroscopic image sequence in order to determine an ablation catheter tip location in each frame. | 03-05-2009 |

20080279420 | VIDEO AND AUDIO MONITORING FOR SYNDROMIC SURVEILLANCE FOR INFECTIOUS DISEASES - We present, in exemplary embodiments of the present invention, novel systems and methods for syndromic surveillance that can automatically monitor symptoms that may be associated with the early presentation of a syndrome (e.g., fever, coughing, sneezing, runny nose, sniffling, rashes). Although not so limited, the novel surveillance systems described herein can be placed in common areas occupied by a crowd of people, in accordance with local and national laws applicable to such surveillance. Common areas may include public areas (e.g., an airport, train station, sports arena) and private areas (e.g., a doctor's waiting room). The monitored symptoms may be transmitted to a responder (e.g., a person, an information system) outside of the surveillance system, such that the responder can take appropriate action to identifying, treat and quarantine potentially infected individuals, as necessary. | 11-13-2008 |

20120232384 | Method and System for Tracking of a Virtual Electrode on a Coronary Sinus Catheter in Fluoroscopic Images - A method and system for detecting a virtual electrode (VE) on a coronary sinus (CS) catheter in a fluoroscopic image sequence is disclosed. User inputs indicating locations of CS catheter electrodes and a location of a VE are received. A catheter electrode model and a VE part model is initialized in a first frame of the fluoroscopic image sequence. The VE is tracked by detecting electrode position candidates and catheter body point candidates in the subsequent frames of the fluoroscopic image sequence using respective trained detectors, tracking the catheter electrode model in the subsequent frames based on the detected electrode position candidates, generating VE part hypotheses in the subsequent frames based on detection of the most proximal electrode (MPE) in each subsequent frame, calculating a probability score for each of the VE part hypotheses, and selecting an VE part hypothesis with the highest probability score. | 09-13-2012 |
