December 4, 2019 at 3:30am - Remote Sensing Research Applications in the USDA Long-Term Agroecosystem Research (LTAR) Network

Carlson Auditorium, 76-1125
December 4, 2019 at 3:30am

Presented by Dr. Alisa Coffin
Research Ecologist with the USDA-ARS Southeast Watershed Research Laboratory in Tifton, Georgia
Adjunct Assistant Professor, University of Georgia

Abstract

The Long-Term Agroecosystem Research (LTAR) network was established in 2012 to facilitate long term research into the sustainable intensification of agriculture in the United States of America (US). Research sites established at eighteen locations across the conterminous US are engaging in a common experimental strategy to evaluate existing and potential agricultural production systems across domains of production, environmental management and rural prosperity. Experimental work at LTAR locations occurs at plot, field and enterprise scales, providing highly detailed information in both space and time about the responses of production systems to experimental manipulations.

To accomplish this work, remote sensing is used to extrapolate local measurements to broader landscape and regional scales, and to record observations across broader areas where direct measurements cannot be obtained. Currently, sites within the LTAR network are using remote sensing for a variety of applications related to crop and forage production. In addition to freely available mid- and coarse- resolution satellite imagery, LTAR remote sensing tools include sensors affixed to towers, unmanned aerial systems, and field-portable spectroradiometers. Remote sensing products have been or are being used in LTAR to: model production in working lands across broad areas; estimate regional water use and stress, snowpack, soil moisture and productivity; map fine-scale vegetation patterns in grazing lands; assess pollinator habitat near crop lands; and capture continuous phenology of crop and forage species.

Considerable challenges being addressed by the LTAR network are related to: data coordination and management of big data across the network; identifying and testing workflows that provide statistically valid and meaningful results about agricultural sustainability and food security; and deploying artificial intelligence that enables the balanced integration of small, slow, clear data streams with big, fast, noisy data rivers to derive useful information that can guide US agricultural policy. Clearly, remote sensing is an indispensable tool for agricultural research, but the role of remote sensing in resolving these data integration issues for LTAR is still taking shape. Addressing these challenges will require considering how remote sensing contributes to LTAR data products, ensuring that image processing methods, including calibration and quality control, are incorporated into in LTAR research workflows, and considering how remote sensing products provide a spatio-temporal framework for integrating diverse data sources.

November 20, 2019 at 3:30am - Image-Based Planning and Guidance of Bronchoscopy for the Chest

Carlson Auditorium, 76-1125
November 20, 2019 at 3:30am

Abstract

Lung cancer is the leading cause of cancer death worldwide, accounting for over one million deaths each year.  Many technical innovations in radiologic imaging and endoscopy have emerged recently in the effort against lung cancer.  In particular, modern radiologic imaging scanners provide three-dimensional high-resolution X-ray CT and PET images of the chest (CT = computed tomography; PET = positron emission tomography).  In addition, modern bronchoscopes enable deep navigation into the lung airway tree, while giving vivid video inside the airways and ultrasonic views outside the airways.  Nevertheless, despite the availability of these tools, the 5-year lung-cancer survival rate remains under 15%.  Our laboratory has worked toward constructing image-guided bronchoscopy (IGB) systems for the purpose of diagnosing and staging lung cancer. Our work combines methods from many branches of imaging science, including image processing, computer vision, computer graphics, and pattern recognition.  Extensive studies over the years have shown the efficacy of our efforts for accurate minimally invasive lung-cancer diagnosis and staging.  In particular, our results show: (1) system ease to use, independent of physician skill level; and (2) markedly higher procedure success than current practice. Our research has also led to the development of FDA-approved commercial systems used worldwide.  This talk will highlight our overall IGB system effort, including basic research, experimental results, and entrepreneurial research translation.

November 13, 2019 at 3:30pm - How you Look at it Matters: Investigations in Hyperspectral BRDF and the Role of Serendipity in Research - Dr. Craig Coburn

Carlson Auditorium, 76-1125
November 13, 2019 at 3:30pm

The increasing reliance on optical remote sensing data to provide essential data for management and modelling of our planet has opened up many opportunities for research in remote sensing.  It has also drawn attention to the complexity of that these data represent.  In this talk, Professor Coburn will address past research into the effects and impacts of spectral reflectance variability with respect to view and illumination angles.  Research into the complex nature of a surface’s spectral reflectance field has always been hampered by lack of available instruments to conduct the measurements – it has also been restricted due to larger and more pressing questions in the science.  Has the time come to begin re-writing these basic constructs?

About the Speaker

Dr. Coburn is a remote sensing scientist working in the Department of Geography at the University of Lethbridge since 2002.  With over 20 years of remote sensing experience, Dr. Coburn focuses his research efforts on the fundamental aspects of remote sensing science, with specific interests in low-cost remote sensing solutions and remote sensing instrument development.  Recently this research has involved studying the nature of surface bidirectional spectral reflectance properties.  This research has led to the development of various instruments for the sampling of surface BRDF primarily for use in understanding agricultural crops and other biological systems as well as efforts in the calibration and validation of remote sensing instruments.

 

November 6, 2019 at 3:30pm - From Oracle Bones to Magna Carta - Imaging Science at the British Library

Carlson Auditorium, 76-1125
November 6, 2019 at 3:30pm

Abstract

The British Library is the national library of the United Kingdom holding over 150 million items with an additional three million new items added annually. The 625 km of shelving includes manuscripts, maps, newspapers, magazines, prints, drawings, music scores and patents. The fundamental purpose of the Library is to make intellectual heritage accessible for research, inspiration and enjoyment. It is therefore imperative that these texts are legible.

The sheer variety of substrate material (paper, parchment, papyrus, bone, leather etc.) and writing material (pencil, iron-gall ink, carbon-ink, pigment etc.) presents an incredible challenge to imaging. In 2012, a new role of Conservation Research Imaging Scientist was introduced to develop strategies and solutions to resolve issues of illegibility. One of the imaging techniques adopted by the Library - multi-spectral imaging (MSI), has proven an invaluable aid to scholars.

MSI has been used on some of the Library’s most significant Treasures and has enabled discovery of a fugitive figure on a folio of Leonardo da Vinci’s notebook, brought new interpretations of the illuminations of the 14th century anonymous poem Sir Gawain & the Green Knight (one of the masterpieces of Middle English literature) to light, as well as recovering text on one of the four original 1215 Magna Carta manuscripts; the Canterbury Magna Carta.

Other imaging techniques such as micro-computed tomography have enabled 3D interpretation of items including St Cuthbert Gospel; an early 8th-century pocket gospel book written in Latin. Its finely decorated leather binding is the earliest known Western bookbinding to survive thanks to being hidden in St Cuthbert’s coffin for several years during the Viking invasions. Further processing of CT datasets has enabled true condition assessments of the Library’s oldest collection items – Chinese Oracle bones, which were used for divination over three thousand years ago.

Through a combination of multi-spectral imaging and post-processing imaging techniques, some of the primary challenges posed by fire-damaged, naturally faded and chemically damaged materials at the British Library are being overcome. This has improved accessibility, conservation and preservation practices.

October 23, 2019 at 3:30pm - Small Data, Big Insights

Carlson Auditorium, 76-1125
October 23, 2019 at 3:30pm

Abstract: Deep learning has defined the state of the art for many computer vision tasks, thanks to advances in computing hardware and the availability of large datasets. However, for many practical applications, data acquisition and annotation can be a laborious and expensive task. This is especially true in specialized fields such as medical imaging, where annotation must be carried out by domain experts. I will describe a series of novel approaches developed at PARC to address the “Small Data” problem. This includes i) incorporating domain-specific regularizers into deep networks for robustness to sparse training; ii) data augmentation via regularized generative models; iii) automatic image annotation based on pre-trained model ensembles; iv) interactive scene annotation with augmented reality; and v) bringing the human into the loop for high quality image acquisition.

October 16, 2019 at 3:30pm - Compressive Sensing for Quantum Imaging

Carlson Auditorium, 76-1125
October 16, 2019 at 3:30pm

Compressive sensing (CS) is an exciting measurement technique that effectively compresses data while it is being measured, allowing high-dimensional signals to be recovered from very few measurements. The CS approach of figuring out how to "just measure the important information" has upended traditional views on sampling and sparked enormous multidisciplinary interest over the past decade.  Remarkably, the best measurements an experimenter can use are often random.  In this talk, I will introduce the basic principles of CS and describe how it can be applied to some current problems in quantum imaging. These range from the very applied, such as how to take a picture using only one photon per pixel, to the very fundamental, such as how to characterize photonic quantum entanglement.

Carlson Auditorium, 76-1125
September 25, 2019 at 3:30pm

Abstract

DLP® technology has been widely used in various display products since it was introduced to the market in 1996 by Texas Instruments. It has revolutionized the century-old movie industry by replacing the traditional film with the digital display technology. The heart of the DLP® technology is the digital micromirror device (DMD), an optical microelectromechanical system, which features an addressable array of up to 8 million microscopic mirrors. This presentation will cover the design, fabrication, packaging, characterization, and reliability of the DMDs. I will discuss the challenges and solutions of several major milestones of DMD development from the micromirror design and operation point of view. Applications of the DMD in nontraditional display technologies, such as compressive line sensing-based underwater imaging technology, will be shared with the audience.

September 18, 2019 at 3:30pm - Hyperspectral Imaging Applications and Novel Sensor Development

Carlson Auditorium, 76-1125
September 18, 2019 at 3:30pm

Abstract

This seminar presents an application-driven approach to novel hyperspectral imaging sensor design. Brief summaries of hyperspectral imaging modalities and their relative performance are presented. Spectro-radiometric signature models are then discussed in the context of sensor and detection algorithm requirements definition. Specifically, how do we design a hyperspectral sensor with sufficient sensitivity and specificity to meet the application requirements? How do we choose the optimal sensor modality given a concept of operation or deployment? What are the size, weight, power and cost considerations? This design process is then illustrated in a discussion of two prototype systems: a UAS-borne visible/near infrared-shortwave infrared hyperspectral imager for vegetation trait mapping, and a longwave infrared hyperspectral imager employing compressive sensing and a single pixel architecture for chemical plume imaging.

September 11, 2019 at 3:30am - The Anomalous Origin of Polymer Enhanced Oil Recovery

Carlson Auditorium, 76-1125
September 11, 2019 at 3:30am

Abstract: Polymer flooding is one of the most economically viable methods for enhanced oil recovery. It is typically used in reservoirs where recovery of oil by water injection declines. Polymer enhanced oil recovery is achieved by flowing a small volume of a polymer solution into the reservoir, followed by more water. Although polymer flooding is primarily developed for increasing the viscosity of the displacing fluid to match that of the oil, enhanced recovery is observed for oils as much as two orders of magnitude more viscous than the polymer solution with surprisingly significant recovery during the second water. To understand this behavior, we use confocal microscopy and particle tracking to determine the velocities of the displacing fluid around trapped oil in a 3D micromodel of porous medium. We find that some polymer is retained in the medium resulting in reduction in the permeability and large and heterogenous changes in the local fluid velocities with as much as an order of magnitude increase in some pores, leading to further mobilization of trapped oil.

About the Speaker: Shima Parsa is an assistant professor of Physics at Rochester Institute of Technology. She has joined RIT in 2019 after her postdoctoral fellowship at Harvard University, where she studied dynamics of multiphase flow in porous media with applications in oil recovery. Shima completed her PhD in Physics at Wesleyan University, where she studied the dynamics of anisotropic particles in turbulence. She is an experimental Physicist with a passion for developing observational and imaging techniques to study Soft Matter. Her research at RIT spans from microfluidics to large scale sedimentation in river with a focus on understanding the fundamental physics of interaction between many bodies mediated by fluid flow.
