 | FIU research concentrated in the following areas of development: nanoelectronics, bio-nanosensors, and nanomaterials, processes, and characterization. Five projects were supported: next generation information storage devices-both three-dimensional magnetic and protein-based, high power cold cathodes for microwave generators, carbon nanotube-based bio-sensors, silicon/polymer nanophotonics, and doped nanodiamonds and nanoceramic lasers for future devices. In magnetic storage devices, this work has resulted in patterned soft underlayer metallizations to localize the recording and sensitivity fields ... |

| Studying the social and cultural transmission of behavior among animals helps to identify patterns and content of interaction. Killer whales likely acquire traits culturally based on their stable social groups, population-specific feeding behaviors, and group-distinctive vocal repertoires. Digital tags were used to record the movements and vocalizations of Norwegian killer whales. These animals carousel feed, corralling herring into a ball before tail slapping, incapacitating and eating the fish. Periods of ... |

Trevor D. McLemore; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| This thesis addresses a two-person, zero-sum game between an intruder and a defender of a military installation. The intruder attempts to penetrate the military installation by choosing one of its many entry points, each of which is monitored by a surveillance camera and may require a different amount of time to transit. Although the real-time video of each surveillance camera is fed to a surveillance room simultaneously, the defender has ... |

| A SIMULINK-based algorithm for monitoring contacts in a surveillance video sequence using Optical Flow Analysis and Kalman Filters was developed. The Horn-Schunk Optical Flow Algorithm was used to identify contacts in a surveillance video sequence. The position and behavior of these contacts was monitored by a modification of the traditional Kalman Filter. The Kalman Filter algorithm implemented has the ability to track up to ten contacts at a time correctly ... |

| Operations and intelligence organizations continue to struggle with how to best plan and employ assets with a video capability. Many heated debates have occurred concerning manned and unmanned, as well as, armed and unarmed assets. This friction caused the less than optimum utilization of these assets. In today's Global War on Terrorism, timely, detailed intelligence is ever more critical to mission success. In many cases, operational commanders do not conduct ... |

| We have measured the temporal response of a commercial liquid crystal on silicon (LCoS) projector, and have compared it to that of commercial liquid crystal display (LCD) and cathode ray tube (CRT) projectors, as well as to a prototype laser projector. The faster temporal response of LCoS displays, as compared to more conventional LCDs, has not been considered a major factor in their commercial use, and so individual pixels are ... |

| Testing to quantify the performance of a soft recovery system was conducted at the U.S. Army Research Laboratory's Transonic Experimental Facility. An on-board recorder (OBR) was inserted into 10 of the 14 rounds fired. Recovery of the OBR equated to recovering the projectile. This necessitated a soft recovery system for the 120-mm projectile. This report details the hardware and methodology used to create a soft recovery and notes about the ... |

| This research effort is focusing on development of adaptive sensing algorithms for asymmetric threats. The algorithms are particularly targeted towards use with data from multi-camera video surveillance systems. We are not attempting to model the infinite class of asymmetric targets, since these are generally unpredictable and therefore limited if any a priori sensor data are available for these threats. Rather, we model normal or typical behavior using statistical algorithms. Key ... |

| We present a discussion of the science drivers and design approach for a high-resolution, mid-infrared spectrograph for the Thirty-Meter Telescope. The instrument will be integrated with an adaptive optics system optimized for the mid-infrared; as a consequence it is not significantly larger or more complex than similar instruments designed for use on smaller telescopes. The high spatial and spectral resolution possible with such a design provides a unique scientific capability. ... |

|
| Video cameras must produce images at a reasonable frame-rate and with a reasonable depth of field. These requirements impose fundamental physical limits on the spatial resolution of the image detector. As a result, current cameras produce videos with a very low resolution. The resolution of videos can be computationally enhanced by moving the camera and applying super-resolution reconstruction algorithms. However, a moving camera introduces motion blur, which limits super-resolution quality. ... |

| The authors present a basic technique to fill in missing parts of a video sequence taken from a static camera. Two important cases are considered. The first case is concerned with the removal of nonstationary objects that occlude a stationary background. For this problem the authors use a priority-based spatio-temporal synthesis scheme for inpainting the stationary background. The second and more difficult case involves filling in moving objects when they ... |

| It has been a long-standing challenge to make Internet audio/video broadcasting a commodity service. This means that anyone with a commodity Internet connection and computer equipment can broadcast high-quality video to a large group of receivers in real time. The key challenge is the bandwidth cost in distributing the video streams. To distribute 300 Kbps video stream to 100 receivers directly, a publisher must provision 30 Mbps bandwidth to the ... |

| Substantial performance improvement of a wide area video surveillance network can be obtained with the addition of a Line-of-Sight sensor. The research described in this thesis shows that while the Line-of-Sight sensor cannot monitor areas with the ubiquity of video cameras alone, the combined network produces substantially fewer false alarms and superior location precision for numerous moving people than video. Recent progress in the fabrication of inexpensive, robust CMOS-based video ... |

| The purpose of this report is to document a procedure for selecting data pairs for analysis from Broadband Array Spectrograph System (BASS) data. BASS data are sometimes contaminated by aircraft or fauna entering the telescope beam during observations, obscuring the spectral signature of the object being measured. This procedure provides a mathematical method for identifying data pairs for exclusion from the subsequent analysis that may have been corrupted. |

| The embedded systems group at Princeton University is building a distributed system for real-time analysis of video from multiple cameras. Most work in multiple-camera video systems relies on centralized processing. However, performing video computations at a central server has several disadvantages: it introduces latency that reduces the response time of the video system; it increases the amount of buffer memory required; and it consumes network bandwidth. These problems cause centralized ... |

| Pre-recorded video segments can be very compelling for a variety of immersive training purposes, including providing answers to questions in after- action reviews. Answering questions fluently using pre-recorded video poses challenges, however. When humans interact, answers are constructed after questions are posed.
