20130010111 | Effortless Navigation Across Cameras and Cooperative Control of Cameras - This application discloses a system and related methods (called Fast Track) to effortlessly navigate across multiple cameras, e.g. video surveillance cameras distributed in a facility. Fast Track simplifies the act of following a suspicious individual roaming in a facility, e.g. by eliminating the need for security operators to memorize camera placement and coverage, and to manually control pan-tilt-zoom (hereinafter “PTZ”) cameras, and by simplifying the process to reduce the risk of operator error. Combinations of novel scoring and control methods generally provide an automatic identification of optimal cameras and pre-emptive re-direction of PTZ cameras. Extensions to these methods enable two new capabilities: Cooperative PTZ Control (e.g. coordinating PTZs to cover a 3D map viewport optimally) and Self-Healing Perimeters, to automatically reassign and redirect multiple PTZ cameras to fill gaps in a security perimeter. | 01-10-2013 |
20130021445 | Camera Projection Meshes - A 3D rendering method is proposed to increase the performance when projecting and compositing multiple images or video sequences from real-world cameras on top of a precise 3D model of the real world. Unlike previous methods that relied on shadow-mapping and that were limited in performance due to the need to re-render the complex scene multiple times per frame, the proposed method uses, for each camera, one Camera Projection Mesh (“CPM”) of fixed and limited complexity per camera. The CPM that surrounds each camera is effectively molded over the surrounding 3D world surfaces or areas visible from the video camera. Rendering and compositing of the CPMs may be entirely performed on the Graphic Processing Unit (“GPU”) using custom shaders for optimal performance. The method also enables improved view-shed analysis and fast visualization of the coverage of multiple cameras. | 01-24-2013 |

20090075402 | Manipulation of focused heating source based on in situ optical measurements - A method, system or the like which may, for example, be exploited as part of known methods, systems and/or apparatii which manipulate (i.e. tune, modify, change, create, etc.) the impedance of (integrated) semiconductor components or devices by exploiting a focused heating source. The method, system or the like exploits in situ optical measurements for the modification of the energy output of a focused heating source, such as for example of a (pulsed) laser heat source. The energy input to the focused heating source may be manipulated as a function of an optical measurement so as to obtain a desired or necessary energy output (e.g. target energy output) from the focused heating source. | 03-19-2009 |
