20120114180 | Identification Of Objects In A 3D Video Using Non/Over Reflective Clothing - A computing system generates a depth map from at least one image, detects objects in the depth map, and identifies anomalies in the objects from the depth map. Another computing system identifies at least one anomaly in an object in a depth map, and uses the anomaly to identify future occurrences of the object. A system includes a three dimensional (3D) imaging system to generate a depth map from at least one image, an object detector to detect objects within the depth map, and an anomaly detector to detect anomalies in the detected objects, wherein the anomalies are logical gaps and/or logical protrusions in the depth map. | 05-10-2012 |
20120086781 | 3D Vision On A Chip - A 3D camera for determining distances to regions in a scene wherein gating or modulating apparatus for the 3D camera is incorporated on a photosurface of the camera on which light detectors of the camera are also situated. Each pixel in the photosurface may include its own pixel circuit for gating the pixel on or off or for modulating the sensitivity of the pixel to incident light. The circuit may comprise at least one amplifier inside the pixel, at least one feedback capacitor separate from the light sensitive element and connected between the input and output of each of the at least one amplifier, and at least one controllable connection through which current flows from the light sensitive element into the input of the at least one amplifier. The 3D camera may further include a light source and a controller. | 04-12-2012 |
20110276559 | METHOD FOR IMPROVING SEARCH EFFICIENCY IN ENTERPRISE SEARCH SYSTEM - A search system with a search engine applies a user search query to an index of the documents stored in a document repository for returning a result set of matching documents to a user. In order to more efficiently access, search and retrieve documents stored in document repositories, one of a document repository and an index thereof or both are partitioned in one or more dimensions, and a partition is configured in a specific dimension according to two or more document attribute values selected from one and the same attribute category. This shall enable a search application to access significantly less data in order to determine a search result and shall specifically improve the efficiency of enterprise search systems in a high degree. | 11-10-2011 |
