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.

Open-Source, Platform-Neutral BLAS Library

This work seeks to create libraries that are truly cross-platform, and support hardware from different manufacturers of different generations. Goddard Space Flight Center, Greenbelt, Maryland New hybrid computing systems consist of a multicore CPU (central processing unit) and one or more massively parallel accelerator devices, such as GPUs (graphics processing units). Effectively utilizing these systems involves using all of the available computational resources, which may be difficult to program. Computing libraries have long existed to alleviate programmer burden and to provide high-performing and tested implementations for common tasks. Unfortunately, the library space is very fragmented, even in cases where the libraries cover similar functionality. In the accelerated computing space, this is compounded by different libraries and manufacturer-specific products that are used, all of which are incompatible with one another. The work described here seeks to overcome much of this burden, by creating libraries that are truly cross-platform, supporting hardware from different manufacturers, of different generations, and of differing levels of parallelism.

JPL Unified Methodology Process (JUMP)

This is a unique rapid development framework, complete with checklists, schedules, and supporting procedures. NASA’s Jet Propulsion Laboratory, Pasadena, California JPL Unified Methodology Process (JUMP) is an effort to establish a common frame of reference across OCIO (Office of Chief Information Officer) and EBIS (Enterprise Business Information Services Division). The iterative approach to project management is more powerful and efficient, enables better reviews, and incurs lower overhead costs. JUMP is a tailored version of rational unified process (RUP) and the iterative process. This process is flexible, scalable, and manageable.

A RESTful Web Service Connector for Phoenix Analysis Server

The Web service connects front-end user interfaces to the back-end analysis executions. NASA’s Jet Propulsion Laboratory, Pasadena, California Engineering design models are normally developed using specific modeling tools such as Excel, Matlab, Maple, and Mathematica. It is difficult to connect various models written in different modeling environments and produce results without extensive effort. Phoenix ModelCenter is a commercial tool that can perform this kind of operation on a single desktop computer via a graphical user interface.
