Detection of Carried and Dropped Objects in Surveillance Video

This software analyzes a video input stream and automatically detects carried and dropped objects in near-real-time. NASA’s Jet Propulsion Laboratory, Pasadena, California DARPA’s Mind’s Eye Program aims to develop a smart camera surveillance system that can autonomously monitor a scene and report back human-readable text descriptions of activities that occur in the video. An important aspect is whether objects are brought into the scene, exchanged between persons, left behind, picked up, etc. While some objects can be detected with an object-specific recognizer, many others are not well suited for this type of approach. For example, a carried object may be too small relative to the resolution of the camera to be easily identifiable, or an unusual object, such as an improvised explosive device, may be too rare or unique in its appearance to have a dedicated recognizer. Hence, a generic object detection capability, which can locate objects without a specific model of what to look for, is used. This approach can detect objects even when partially occluded or overlapping with humans in the scene.

Signal Processing Software for Remote Vital Sign Monitoring

NASA’s Jet Propulsion Laboratory, Pasadena, California This software provides the processing for a non-contact system that remotely estimates the heart rate and respiration rate of individuals as they carry on daily activities, and also enables detection of heart and respiration rate through walls.

Visualization of fMRI Network Data

NASA’s Jet Propulsion Laboratory, Pasadena, California Functional connections within the brain can be revealed through functional magnetic resonance imaging (fMRI), which shows simultaneous activations of blood flow in the brain during response tests. However, fMRI specialists currently do not have a tool for visualizing the complex data that comes from fMRI scans. They work with correlation matrices that table what functional region connections exist, but they have no corresponding visualization.

Artificial Immune System-Based Approach for Air Combat Maneuvering

The primary motivation for this research is to enable unmanned aircraft with intelligent maneuvering capabilities. Ames Research Center, Moffett Field, California A high level of autonomy is desired for future unmanned combat systems because lethality and survivability can be improved with much less communication bandwidth than would be necessary for preprogrammed or remotely operated systems. However, there are a number of technical challenges that must be addressed prior to implementation.

Rule-Based Analytic Asset Management for Space Exploration Systems (RAMSES)

Radio Frequency Identification (RFID) systems have applications in tracking and managing small shipping containers and packages in the commercial supply chain. Stennis Space Center, Mississippi Human space systems, such as the International Space Station (ISS) and future planned missions to the lunar surface and beyond, require the crew’s ability to locate and manage the physical resources that are required for use to achieve mission objectives. However, the large number of assets, ranging from expensive, specialized equipment, to food, water, and medical consumables for the crew is an overwhelming management problem. These assets are stored in numerous containers that are sometimes nested within other containers, frequently removed from one container and placed in another location, consumed, and/or used, and then discarded. Additionally, sometimes the containers themselves are moved. The challenge is to track and manage these assets so that the crew can readily locate items and ground controllers can identify when there is a need to provide sufficient resupply for the mission.

Post-Flight Analysis Statistical Heating (PFlASH)

Lyndon B. Johnson Space Center, Houston, Texas This software tool automates the statistical analysis of heating indicators for a family of trajectories. It allows for quick and clear relative comparison of the trajectories by concisely and meaningfully reducing an arbitrarily large set of body point heating into single values that are used to rank the trajectories. This software is user friendly, and enables other engineers to easily perform analysis. PFlASH post-processes the XF0002 Dump7 files or QLIST to calculate heating indicators and statistics on the heating indicators. PFlASH automatically generates Matlab.m files to produce presentation-quality plots that are ready to be inserted into briefings or collated into a pdf.
