20100202543 | COMMUNICATION SYSTEM AND METHOD OF OPERATIONS THEREFOR - A method of operation in a communication system is presented in which a first terminal sends to a second terminal a communication including ranging information by which the second terminal is able to calculate a range between the first terminal and the second terminal. The communication is sent in a plurality of frames. In at least one of the frames ranging information is included in a ranging region of the frame. The size and position of the ranging region is known to the first and second terminals without a ranging information indicator being sent in the frame to indicate the size and position of the ranging region. | 08-12-2010 |

20140111511 | SYSTEM AND METHOD FOR MULTIPLE HYPOTHESES TESTING FOR SURFACE ORIENTATION DURING 3D POINT CLOUD EXTRACTION FROM 2D IMAGERY - The system and methods described herein operate on a plurality of images that include multiple views of the same scene, typically from slightly different viewing angles and/or lighting conditions. One of the images is selected as a reference image. For each image ray in a non-reference image, the system and methods resample a local region from the non-reference image's space to the reference image's space. The resampling is performed multiple times, each time with a different surface orientation hypothesis. The system and methods run cross-correlation style correlators on the resampled images, evaluate correlation scores for each of the resampled images, and select the surface orientation hypothesis associated with the highest correlation score. The system and methods project a peak of the correlation surface back through a geometry model for the selected surface orientation hypothesis to determine a three-dimensional (ground) location for the image ray. | 04-24-2014 |
20140253543 | PERFORMANCE PREDICTION FOR GENERATION OF POINT CLOUDS FROM PASSIVE IMAGERY - A system and method of generating point clouds from passive images. Image clusters are formed, wherein each image cluster includes two or more passive images selected from a set of passive images. Quality of the point cloud that could be generated from each image cluster is predicted for each image cluster based on a performance prediction score for each image cluster. A subset of image clusters is selected for further processing based on their performance prediction scores. A mission-specific quality score is determined for each point cloud generated and the point cloud with the highest quality score is selected for storage. | 09-11-2014 |
