Detecting and Analyzing Discontinuities in Computer Vision @ University of California-Santa Barbara The research in this project will develop robust and effective algorithms for detecting and analyzing meaningful image discontinuities, which are critical cues that play an important part in building general image understanding systems. The project will build on promising preliminary research on multi-flash imaging, which uses active illumination to achieve robust detection and labeling of depth discontinuities in images. These ideas will be generalized by varying various aspects of the illumination parameters and developing methods to handle a much wider variety of imaging conditions. The research will develop a framework for robust multi-view stereo by integrating viewpoint variation with active illumination, and it will extend the concept to develop methods for detecting and analyzing other kinds of meaningful discontinuities (in surface normal, illumination, motion, etc.). To pursue these objectives, extensive data collection and experimentation will be performed with a number of image capture designs and methods for detecting and analyzing discontinuities. The research will enable a variety of both short-term and long-term applications in engineering, medicine, art, and entertainment. Real and synthetic data for experiments will be shared publicly with the research community via the web, as will metrics and software for comparing and evaluating techniques. The educational impacts of the project include the involvement of graduate and undergraduate students and new seminar courses that will be developed related to the research theme. The project will address diversity issues by recruiting undergraduate researchers and short-term graduate students through programs that aim to increase the involvement of underrepresented students in science and engineering, and also by the planned collaborations with colleagues and students in areas outside of Computer Science where women are currently better represented. |

@ University of California-Santa Barbara In this research project, the PI proposes to develop novel methodology to visualize and interact with large interconnected high-dimensional datasets represented as large unstructured graphs. The underlying semantics for the nodes and edges in such a graph are to be kept flexible, but the ultimate goal is for an analyst to acquire an understanding of the data universe as a whole, and to enable him or her to issue and resolve specific data queries. An analyst should also have an easy way to inform a colleague about the insights gathered during their own interaction with the system, including evidence chains and new hypotheses. |

Hcc: Small: Telecollaboration in Physical Spaces @ University of California-Santa Barbara The goal of this project is to develop and evaluate novel methods for telecollaboration - remote collaboration that effectively integrates video and voice communication, computer vision based tracking, and augmented reality display in order to enable participants to more fully leverage the local physical environment in their remote interactions. In this telecollaboration paradigm, remote and local users will interact with the physical environment using models derived from live imagery from a camera that the local user holds or wears, rather than merely passively viewing the video stream. A key aspect of the approach is that it does not require preparation of the environment or model information, so it can be viewed as an "anywhere, anytime" mobile communication technology. |

Si2-Sse: Yt: Reusable Components For Simulating, Analyzing and Visualizing Astrophysical Systems @ University of Illinois At Urbana-Champaign Computational modeling of astrophysical phenomena has grown in sophistication and realism, leading to a diversity of complex simulation platforms, each utilizing its own mechanism and format for representing particles and fluids. Similarly, most of the data analysis is conducted with tools developed in isolation and targeted to a specific simulation platform or research domain; very little systematic and direct technology transfer between astrophysical researchers exists. The yt project is a parallel analysis and visualization toolkit designed to support a collaborative community of researchers as they focus on answering physical questions, rather than the technical mechanics of reading, processing and visualizing data formats. This project will enable the development of advanced, physics-based modules that apply universally across simulation codes, advancing scientific inquiry and enabling more efficient utilization of computational and human resources. In doing so, it will help advance a myriad of research goals from the study of black hole binaries to the growth of cosmic structure. In addition, the project will serve as a touchstone for collaboration and cross-code utilization between many groups studying diverse phenomena. Moreover, the project will be developed through a community-oriented process, engaging a wide range of participants. |

@ University of Illinois At Urbana-Champaign A great challenge in astrophysics is to understand in detail how the initial smooth distribution of matter in the early Universe formed the first galaxies. Complementing observations of real galaxies, researchers use computational simulations to model the early Universe and study the results. This process allows one to learn how these first galaxies might have formed. However, the sheer size and complexity of such galaxy simulations present their own challenge as a single research group lacks the capacity to explore them fully. As a result, maximizing the scientific value of simulations demands new tools and services designed to foster the growth of a collaborative, multi-group research community. This project aims to develop and use a new virtual laboratory to enable transformative scientific inquiry on new and existing galaxy simulations, some of which were produced by prior NSF support. Enabling public access and unrestricted analysis and fostering a collaborative environment for sharing technology and results will ensure that galaxy simulations continue to be valuable within and beyond the research group that originally conducted them. This project addresses the national imperative to develop US cyber infrastructure and to develop US leadership in scientific research in astrophysics. |

Cc*Dni Dibbs: Merging Science and Cyberinfrastructure Pathways: the Whole Tale @ University of Illinois At Urbana-Champaign Scholarly publications today are still mostly disconnected from the underlying data and code used to produce the published results and findings, despite an increasing recognition of the need to share all aspects of the research process. As data become more open and transportable, a second layer of research output has emerged, linking research publications to the associated data, possibly along with its provenance. This trend is rapidly followed by a new third layer: communicating the process of inquiry itself by sharing a complete computational narrative that links method descriptions with executable code and data, thereby introducing a new era of reproducible science and accelerated knowledge discovery. In the Whole Tale (WT) project, all of these components are linked and accessible from scholarly publications. The third layer is broad, encompassing numerous research communities through science pathways (e.g., in astronomy, life and earth sciences, materials science, social science), and deep, using interconnected cyberinfrastructure pathways and shared technologies. |

@ University of Illinois At Urbana-Champaign Scientific discovery across the physical sciences is increasingly dependent on the analysis of volumetric - or three-dimensional - data, that may come from a supercomputer simulation, direct measurement, or mathematical models. Researchers typically seek to extract meaningful insights from this data by visualizing and analyzing it in various ways. The ways in which scientists process volumetric data are actually quite similar across domains, but cross-disciplinary knowledge transfer and tool development is blocked by barriers of terminology. This project seeks to enhance an analysis and visualization toolkit named yt that is currently primarily used for astrophysical simulations. yt allows scientists to access and analyze data at several different levels by providing an interface that is designed to answer questions motivated by the underlying scientific problem, while worrying less about details such data formats, specific analysis techniques etc. yt's utilization in computational astrophysics has dramatically increased access to advanced algorithms for both visualization and analysis, and fostered the growth of a community of researchers sharing techniques and results. This project seeks to make yt available and adopted by scientists in other domains of science thus reproducing its success in astrophysics in these other science domains. This project will expand the yt community beyond theoretical astrophysics and enable and promote collaboration and advanced data analysis in the fields of meteorology, seismology and global tomography, observational astronomy, hydrology and oceanography, and plasma physics. |

Eager: Attention-Aware Mixed Reality Interfaces @ University of California-Santa Barbara This project develops new technologies that measure and model people's state of attention and applies these methodologies to virtual reality (VR) and augmented reality (AR) language learning applications. For determining the degree of people's attention on central learning tasks presented in VR and AR, this project uses two sensor modalities that can index attention: electrical activity of the brain, as measured by electroencephalography (EEG) signals, and eye gaze behavior, as measured by eye trackers. Context recognition plays a key element in future VR and AR application scenarios, and users, as well as content providers, can benefit substantially from information about user attention states during information consumption. The project can inform the development of optimized VR and AR content, as well as individualized learning strategies. The project's motivating application is the optimization of language learning for users across the complete spectrum of ability. In the longer run, additional benefits include the creation of special tools for students with known attention deficits, as well as for increasing productivity and safety in various commercial and industrial applications. |

Nrt-Hdr: Data and Informatics Graduate Intern-Traineeship: Materials At the Atomic Scale (Digi-Mat) @ University of Illinois At Urbana-Champaign The application of engineering materials impacts every facet of society, through manufacturing, energy, transportation, medicine, and more. One the most important trends in materials science is the emergence of atomic scale characterization of materials. Characterizing and modeling materials at the atomic scale generates massive data sets. New advances in data science are now revolutionizing the way that materials data are captured, curated, managed, and manipulated. Industry and national labs are increasingly in need of a science and engineering workforce trained in both materials and data science. This National Science Foundation Research Traineeship (NRT) award to the University of Illinois will support the creation of a Data and Informatics Graduate Intern-Traineeship in Materials at the Atomic Scale (DIGI-MAT). The vision of DIGI-MAT is that materials problems will ultimately be data problems, and understanding of materials will be a challenge in capturing, curating, managing, and manipulating massive data streams. The program will combine cutting-edge research with a new curriculum, professional development opportunities, on-demand skills training, and, at the core of the program, research internships with external partners. This project anticipates training 72 PhD students, including 31 funded trainees, from degree programs in engineering, physics, statistics, and information science. |

Chs: Small: Integrative Wide-Area Augmented Reality Scene Modeling @ University of California-Santa Barbara Augmented reality (AR) is a technology that superimposes computer-generated visual, auditory, or other sensory information onto the physical world, so that they appear to be part of the actual environment. The goal of the proposed project is to develop and evaluate new methods for creating, maintaining, and improving large-scale scene models to enable wide-area AR. For example, consider an AR application for firefighters, which superimposes predicted changes in fire perimeter and coordinated action plans to help them understand weather impact and communicate the current plan of attack. Augmented reality is characterized by the fact that these visualizations are three-dimensionally registered with the real world, keeping them matched to the physical environment in real-time even as the user moves around their environment. In order to place new virtual annotations (and to keep track of previously placed annotations), a three dimensional "scene model" that represents the physical world locations needs to be created. Ideally, this would be done on a global, world-wide scale to include all possible places where AR experiences are possible or have even already occurred. Since it is difficult for one person or organization to collect the data needed for such a wide-area scene, the developed system will aggregate crowd-sourced data of different modalities (e.g., images, videos, and 3D geometrical meshes) from multiple sources, leveraging semantic information in addition to basic image and point cloud data. By providing capabilities for remotely guiding a local AR user to capture new imagery or sensor data to achieve more accurate or complete models, crowd-sourced modeling can be directed over time to create and continuously update scene models of large-scale areas, such as a university campus or even a city. The research will result in a system that effectively integrates multiple components to provide new opportunities to remotely navigate, explore, and augment physical spaces for AR applications in government, education, industry, and consumer spaces. |

@ University of Illinois At Urbana-Champaign Modern laboratories provide unprecedented sensitivity to the many different galactic-messengers that stream through our planet by the minute: cosmic rays, light from distant galaxies, elusive neutrinos, and possibly dark matter. Combining this information with models and data from simulations provides insight into how our universe began and continues to evolve -- the scales at which objects first collapsed, the development of stars and galaxies, and the dynamics within our own galaxy. |

@ University of Illinois At Urbana-Champaign The Earth’s mantle, which sits directly below the crust, is predominantly made of solid rock; yet the solid mantle can flow when pushed or pulled. The rate of this flow depends on the properties of the rock, such as its temperature, and on the nature of the contacts between the tiny mineral crystals that comprise the rock. The mantle can be pushed to flow by numerous different phenomena, such as: passing seismic waves after an earthquake; melting of continental ice sheets and glaciers; the annual cycle of groundwater recharge and extraction; and the draining of large lakes. This study uses observations of these phenomena to measure the rock properties and the interactions between mineral crystals in the mantle beneath three locations: the western United States, Alaska, and Iceland. Meanwhile, laboratory experiments are probing how samples of rock deform under controlled conditions. Finally, new computer models are synthesizing the lab and field observations to understand the underlying physical laws that explain the full suite of data. The results of this study have a bearing on topics that range from predicting how sea level will rise due to melting ice sheets to understanding tidal deformation on Jupiter’s moons. Outreach and training are key elements of the project. Four graduate students and six undergraduate students are being educated over the duration of the project. Workshops will bring together researchers from diverse scientific disciplines to learn and debate about the scientific outcomes and the computer tools developed as part of this study.<br/><br/>There is emerging recognition that the variables describing Earth’s mechanical response to stress, elastic moduli, attenuation, and viscosity, are all frequency dependent. While the end-member elastic and steady-state behaviors are relatively well understood, there remain many fundamental questions regarding the intermediate transient regime. This study is an integrative research and outreach program that combines observational, laboratory, and modeling efforts to measure Earth’s full-spectrum rheological response and illuminate the underlying microphysical processes. Observational work is characterizing frequency dependent upper-mantle dissipation in three locations (western U.S., Iceland, and Alaska) using seismic and geodetic observations of different frequencies but complementary spatial sampling. Experimental work is investigating how dislocations affect transient creep under different temperature and stress conditions and with variable quantities of melt and secondary solid phases. Modeling work is developing new constitutive laws for transient creep and incorporating more sophisticated rheologies in the viscoelastic deformation code. This study is addressing questions about: (1) the broadband mechanical response of the solid Earth; (2) the microphysical processes that control viscoelasticity; and (3) the implications for inferences of steady-state viscosity from geodetic observations and of thermodynamic state from seismic tomography. Broader impacts include training of graduate and undergraduate students, a synthesis workshop that convenes 120 researchers to outline recent advances in understanding transient rheology and to shape the topics and collaborations that will dictate the next decade of inquiry, and development of interactive Jupyter notebooks that introduce open-source data-science tools in the context of seismic attenuation and transient rheology.<br/><br/>This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria. |
