 | Detection and identification of partially occluded targets in complex scenes becomes an increasingly important task in light of the latest developments in urban warfare. The construction of a system that can automatically identify selected targets or direct soldiers attention to the locations that may contain suspicious activity can be of great use not only as a tool that can reduce the cognitive workload of the soldier but also as a ... |

|
| Training systems for emerging threats often require complex, realistic and flexible scenarios. Two recent studies analyzed small boat swarming attacks and found that no adequate training systems exist, particularly since live-firing at multiple targets is impractical. Augmented Reality (AR)-compositing real environments and simulated objects-can overcome this training gap as it allows replacing real ammunition and targets with virtual rounds and boats. Recent advancements in AR address the generation and display ... |

| The peer-to-peer (P2P) training approach involves small groups of people from similar social groupings, who are not professional teachers, helping each other to learn. The P2P approach has great potential for rapidly identifying emerging lessons learned and integrating them into wide-reaching Army training. The present research identified the instructional principles and best practices for P2P from academia, industry, and the military supporting effective P2P training and incorporated them into a ... |

| Distance Learning (DL) is a formal learning activity that occurs when students and instructors are separated by either time or geographical distance. Since the learning and teaching occur in different places, DL requires special course design and instructional techniques, as well as special communication techniques and organizational- administrative arrangements DL programs have various delivery methods using either asynchronous (email, Web, videotape) or synchronous (Video teleconferencing, Elluminate) communications technologies. There are ... |

| This project has two complementary goals: to develop new methods for video tracking using multiple, physically distributed cameras without relying on centralized servers; and to develop new algorithms for tracking using infrared images. We must develop target models for infrared that are robust to changes in target orientation, illumination, and environmental conditions. In general, the best results are obtained by fusing data: fusion of multiple channels, such as visible and ... |

| Our ability to analyze large, complex data sets, such as persistent surveillance data, has often far outstripped our ability to rapidly analyze that data. We have identified a class of intelligent data reduction algorithms, known collectively as Nonlinear Dimensionality Reduction (NLDR), and we believe the utilization of NLDR approaches will allow a significant performance improvement for automated data analysis systems. In this report, we review the basic elements of NLDR ... |

| One method for accurately georegistering a video sequence from an airborne platform is to transform the video to the same coordinate system as some reference imagery that is already georeferenced. This transformation will be dependent upon the 3D structure within the scene, which is not known a priori. The current report examines several aspects of the construction of a 3D model from a video sequence, which may then be used ... |

This would apprise combat decision makers with actual images of battlefield developments and allow them to make sound decisions. To achieve this objective, the characteristics of video traffic must be studied and understood. This thesis focuses on evaluating the possibility of routing video images over a wireless sensor ... |

| A persistent challenge in the High-Performance Computing (HPC) community is how to provide remote visualization capability to its users. A dynamic and economical solution is a KVM-over-IP technology, which uses a pre-existing TCP/IP network to transmit KVM data between two locations. However, the level of performance and functionality present in the current consumer-level KVM-over-IP devices makes them less than desirable for DoD HPC applications. To address the specific needs of ... |

| Modern navigation systems can use the Global Positioning System (GPS) to accurately determine position with precision in some cases bordering on millimeters. Unfortunately, GPS technology is susceptible to jamming, interception, and unavailability indoors or underground. There are several navigation techniques that can be used to navigate during times of GPS unavailability, but there are very few that result in GPS-level precision. One method of achieving high precision navigation without GPS ... |

| Differences in spectral response, pixel size, and noise characteristics between low-light video technologies complicate the direct comparison of field performance for a surveillance application. Commonly measured camera properties such as modulation transfer function and read noise do not directly relate to field performance (e.g., probability of target recognition). In modeling camera field performance based on these measured properties, many assumptions are often made such as constant prereadout gain, signal-independent noise ... |

| The evaporation rates of two decontamination solutions, DeconGreen(TradeMark) and DF200(TradeMark), were measured from surfaces with multiple and independent methods. Evaporation was measured by mass of residual decontaminant and video image processing. A wind tunnel was used to simulate an arid climate, with a low relative humidity and high temperature. The decontamination solution, DF200(TradeMark), evaporated faster from bare and CARC-coated aluminum by a factor of approximately 2.8 compared to DeconGreen(TradeMark). |

We find functions that embed both state and observation into a space where similarity corresponds to L1 distance, and define an observation potential based on distance in this space. This potential is extremely fast to compute and in conjunction with a grid-filtering framework can be used to reduce ... |

These objectives can be accomplished by digital watermarking whereby a digital signature is embedded in imperceptible portions of cover media. Since the marked media may undergo friendly operations such as filtering, compression and scaling the watermark must be robust. One ... |
