| 20090125584 | SYSTEM AND METHOD FOR SPATIO-TEMPORAL-CONTEXT AWARE INTERACTION OF USERS WITH AN ENTITY OF INTEREST - A multifunctional interaction system which is capable of spatio-temporal context localization of users and of communication of audio/video streams to an entity of interest defined by the user, includes a communication domain supporting a predefined localization service, a server associated with the communication domain, client devices, and a dynamically changing context database which is customized in accord with the dynamics of interaction sessions of client devices with the server. The client communicates with the system to either request services therefrom or to send a message to the entity of interest. The system is provided with a panic alert mechanism which, upon actuation, transmits an audio/video data stream along with the client location tag, time stamp, and client ID, to a police precinct for prompt action. | 05-14-2009 |

| 20090244062 | USING PHOTO COLLECTIONS FOR THREE DIMENSIONAL MODELING - A collection of photos and a three-dimensional reconstruction of the photos are used to construct and texture a mesh model. In one embodiment, a first digital image of a first view of a real world scene is analyzed to identify lines in the first view. Among the lines, parallel lines are identified. A three-dimensional vanishing direction in a three-dimensional space is determined based on the parallel lines and an orientation of the digital image in the three-dimensional space. A plane is automatically generated by fitting the plane to the vanishing direction. A rendering of a three-dimensional model with the plane is displayed. Three-dimensional points corresponding to features common to the photos may be used to constrain the plane. The photos may be projected onto the model to provide visual feedback when editing the plane. Furthermore, the photos may be used to texture the model. | 10-01-2009 |
