Image Processing Software Environment (QuIP)

Ames Research Center, Moffett Field, California The QuIP interpreter is a software environment for QUick Image Processing that features an interactive scripting language designed to facilitate use by non-expert users through features such as context-sensitive automatic response completion. The package includes a number of script packages that implement high-level functions such as analysis of eye images for human gaze tracking, medium-level functions such as feature tracking, and low-level functions such as image filtering. The environment also includes facilities for displaying images onscreen, drawing and overlaying graphics, and constructing graphical user interfaces using the scripting language. QuIP can be acquired at: http://scanpath.arc.nasa.gov/quip/.

CubeSat-Compatible, High-Resolution, Thermal Infrared Imager

This imager will consolidate many of the best features in a single technology. Goddard Space Flight Center, Greenbelt, Maryland A small, adaptable, and stable thermal imaging system was developed that can be flown on an aircraft, deployed on the International Space Station as an attached payload, launched on a ride-share as an entirely self-contained 3U CubeSat, flown on a small satellite, or be a co-manifested satellite instrument. When the instrument design is proven, multiple copies of it could be assembled and aligned into an instrument array to enable large-swath thermal imaging from space, all to provide more detailed spatial and temporal data for biomass burning and land surface temperature studies than has heretofore been available from orbit. The instrument has an Earth-observing expected noise equivalent differential temperature (NEDT)

Fabrication and Imaging Method for Microstructured Photonic Belt Resonator

The resonators have application in quantum and nonlinear optical areas where dispersion control is required. NASA’s Jet Propulsion Laboratory, Pasadena, California Frequency combs derived from optical microresonators are required to reach an octave in span. This is required for self-referencing a comb. Presently, the frequency comb span produced by whispering gallery microcavities and other types of cavities is limited mostly by total cavity dispersion.

NASA Vision Workbench (VWB) v3

Ames Research Center, Moffett Field, California VWB is a modular, extensible computer vision framework that supports tasks including automated science and engineering analysis, large satellite image processing, and 2D/3D environment reconstruction. The framework provides a rapid C++ development environment as well as a flexible, multi-platform system to deploy computer vision applications. The module interface allows new capabilities to be rapidly integrated, and a dataflow architecture allows image processing pipelines to be quickly developed and reconfigured.

Flight Proving a Heliophysics Soft X-Ray Imager

Goddard Space Flight Center, Greenbelt, Maryland The interaction between the solar wind and the Earth’s magneto - sphere results in “space weather.” To determine the true nature of the solar wind-magnetosphere interaction, scientists require global measurements of processes occurring at the bow shock, in the magnetosheath, and at the magnetopause. Such observations can only be obtained from imaging this interaction globally. This will produce a paradigm shift similar to how satellite imaging revolutionized terrestrial weather forecasting.

Intensity Interferometry Image Recovery

NASA’s Jet Propulsion Laboratory, Pasadena, California This software extends the well-known error-reduction Gerchberg-Saxton method to imaging of dark objects, assuming that such an object partially shadows a well-characterized thermal light source, while the shadow cannot be used for inferring the object’s shape. These assumptions are reasonable for a wide class of astronomic objects of interest, such as exoplanets, asteroids, neutron stars, dust clouds, black holes, dark matter, etc.

Cameras for All-Sky Meteor Surveillance (CAMS) Version 1.3

Goddard Space Flight Center, Greenbelt, Maryland The CAMS system comprises a deployment of multiple narrow-field, low-light video cameras that completely covers the sky in a mosaic pattern from 30° elevation and above. Two or three such camera batteries separated by many kilometers allow for large atmospheric volume coverage, high spatial resolution, and the high probability of viewing a meteor from more than one site for triangulation and thus atmospheric path reconstruction.

Normalized Cross Correlation FPGA Implementation

NASA’s Jet Propulsion Laboratory, Pasadena, California A safe and precise landing system for Mars will match features seen in descent imagery against a map constructed from orbital imagery. The spacecraft attitude and altitude are known, but lateral position is known only poorly. From attitude and altitude, one can generate a mapping (homography) that allows the descent image to be warped into the orthonormal viewpoint of the map. Since there now will be two images from the same viewpoint, normalized cross correlation can be used to locate in image 2 the positions of features seen in image 1. These are well-known techniques, but this process must be performed ten times a second using relatively slow space-qualified hardware.

Advanced Rapid Imaging and Analysis for Monitoring Hazards (ARIA-MH)

Geodetic imaging capabilities may be brought to a level that will enable NASA scientists and technologists to support local, national, and international hazard response communities. NASA’s Jet Propulsion Laboratory, Pasadena, California Space-based geodetic measurement techniques such as Interferometric Synthetic Aperture Radar (InSAR) and Continuous Global Positioning System (CGPS) are now critical elements in the toolset for monitoring earthquake-generating faults, volcanic eruptions, landslides, glacial ablation, reservoir subsidence, and other natural and man-made hazards. Geodetic imaging’s unique ability to capture surface deformation with high spatial and temporal resolution has revolutionized both earthquake science and volcanology. Continuous monitoring of surface deformation and surface change before, during, and after natural hazards allows for better forecasts, increased situational awareness, and more informed recovery. Combining high-spatial-resolution InSAR products with high-temporal-resolution GPS products, and automating this data preparation and processing across global-scale areas of interest, is an untapped science and monitoring opportunity.

Next-Generation Integrated Camera (NIC)

<NASA’s Jet Propulsion Laboratory, Pasadena, California Design and fabrication of a modern, compact, highly modular, and extreme-environment-capable replacement have been proposed for the Mars Exploration Rover (MER) camera. This next-generation camera is based on a CMOS (complementary metal-oxidesemiconductor) imager rather than a CCD (charge-coupled device) imager, and will provide similar image quality to the MER cameras. At the same time, the NIC will enjoy a higher readout speed, operate over a wider temperature range (–135 °C to 125 °C), and cost less to fabricate while seeing a 10× reduction in mass, size, component count, and power consumption of the camera.
