Method and system for classification in imbalanced datasets within a supervised classification framework. Bootstrap methodology is modified according to k-Nearest Neighbor sampling weights and adaptive target set size principle, to induce weak classifiers from the bootstrap samples in an iterative procedure that results in a set of weak classifiers. A weighted combination scheme is used to adaptively combine the weak classifiers to a strong classifier that achieves good performance for all classes (reflected as high values for metrics such as G-mean and F-score) as well as good overall accuracy.

A method, system, and computer program product for stabilizing frames, the method comprising: receiving a frame sequence comprising three or more frames, including a current frame; determining salient feature points within the frames; matching the salient feature points between the frames; dropping salient feature points associated with advancing objects; dropping salient feature points associated with objects moving in shaking movements; computing a transformation between pairs of consecutive frames from amongst the at least three frames, based upon non-dropped salient feature points, thereby obtaining a multiplicity of transformations; determining a center position for the frames based upon the multiplicity of transformations; determining a stabilizing transformation from a current frame to the center position; and applying the stabilizing transformation to the current frame to obtain a stabilized frame.

A system for face recognition includes a mobile camera that is configured to be carried in a concealed manner by a user. A processor is in communication with the camera and is configured to apply face recognition to an image that is obtained from the camera. The processor is further configured to determine if a notification is to be issued and to issue a notification to a notification device.

The invention provides methods and systems for identifying objects transitioning boundaries defined around geographic areas using sensors. Objects that are vehicles are detected by license plate reader sensors. Boundaries defining geographic zones and sub-zones are pre-defined graphically by reference to a map or computed based on locations of sensors located within the geographic region. When sensor coverage is incomplete, soft zones are computed and defined. Soft zones are computed using probabilistic models, and are developed to minimize the number of escape paths from any sub-zone around sensor locations. Using these probabilistic models, additional sensors can be optimally placed for further enhancement of the detection system.

A method and system of identifying in an image captured by a second camera a target object captured by a first camera is disclosed. The method comprises using image captured by the 1^(st )camera for generating a first set of objects comprising the target object and other objects; classifying each object to generate a reference group of attribute values characterizing the objects; using image captured by the 2^(nd )camera for generating second sets of objects; classifying each object in each second set to generate, for each second set, a corresponding group of attribute values characterizing the objects in the corresponding second set; selecting the second set of objects corresponding to the group of attribute values best matching the reference group of attribute values; and identifying the target object in the selected second set of objects in accordance with a position of the target object in the first set of objects.

A system and method for maintaining and updating a complex event processing system in response to real-world changes, to avoid non-optimal queries that can lead to poor performance and/or erroneous results. The knowledge model of the complex event processing system is monitored to identify elements that impact query optimization and additional knowledge elements that would impact query optimization if they were present. A watch model is constructed for the identified elements, and responses to monitor queries sent to the event processor are checked to determine if the system requires re-optimization. When monitor query responses indicate that the system requires re-optimization, the affected queries are re-optimized and redeployed automatically.

A system and method for intercommunication among the members of a team employing user devices, organized around maps of the locations of the team members presented on the display screens of the user devices. Team members manage intercommunications among themselves by selections made according to the displayed maps and icons thereon. The maps provide a flexible framework around which to structure various modalities of intercommunication including chat, voice, audio-video camera streaming, or a data stream from a sensor, which are graphically indicated on the maps. Organizing and managing according to icons of team members on the maps provides flexible intercommunication without excessive constraint, facilitating intuitive and easy operation. When posting of geographical location of a team member is not desired, a ghost mode permits a team member to freely interact with the group without divulging location.
