Dr. Srijith Rajamohan and Alana Romanella are working on a deep-learning based interactive visualization tool to understand and plot political ideologies based on Twitter activity. They have been collecting data over past four months, analyzing roughly 3 millions tweets based on certain hash tags. The goal of their work is to construct a visualization tool that can help identify political ideology.
Color is fundamental component of the world around us and our experience. It plays a key role in the understanding of our environment, from science and engineering to design and art … but how does it work ? And, what makes digital color different?
This September, renown color and visualization expert Theresa-Marie Rhyne will visit Virginia Tech to share her perspective on the theory and practice of color. With years of experience building notable visualization programs and as the author of the recent book, Applying Color Theory to Digital Media and Visualization, Theresa-Marie will visit with faculty and students as well as give a lecture to a graduate Computer Science class and to the broader University Community. Her talk is scheduled for 1 pm Monday Sept 23rd in Torgersen Hall 1100.
“Color Fundamentals for Digital Content Creation & Visualization”
Abstract: We provide an overview of the fundamentals of color theory and approaches to color selection for visualization and exploration. Our journey includes the introduction to the concepts of color models and harmony, a review of color vision principles, the defining of color gamut, spaces and systems, and highlighting online and mobile apps for performing color analyses of digital media. We feature concepts from art and design such as extending the fundamentals of the Bauhaus into digital media as well as review color perception and appearance principals from vision and visualization researchers and practitioners. Newly emerging trends in automated color selection and deep learning colorization are also noted.
About the Instructor: Theresa-Marie Rhyne is an expert in the field of computer-generated visualization and a consultant who specializes in applying artistic color theories to visualization and digital media. Her book on “Applying Color Theory to Digital Media and Visualization” was published by CRC Press in 2016 and is recognized by librarians and color professionals as a best selling reference. Her short course at the premiere conference on computer graphics and interactive techniques, SIGGRAPH 2019, was standing room only. Theresa-Marie has consulted with the Stanford University Visualization Group on a color suggestion prototype system, the Center for Visualization at the University of California at Davis and the Scientific Computing and Imaging Institute at the University of Utah on applying color theory to ensemble data visualization. Prior to her consulting work, Theresa-Marie founded two visualization centers: (1) the United States Environmental Protection Agency’s Scientific Visualization Center and (2) the Center for Visualization and Analytics at North Carolina State University.
A new collaboration is underway across the Commonwealth of Virginia as the CLAS-12 instrument comes online at Jefferson National Labs: The Center for Nuclear Femtography is a Commonwealth-funded center dedicated to imaging the heart of the atom: the nucleon. In 2018, researchers from around the state were called to the first annual Symposium on Nuclear Femtography, held in Charlottesville; later that year, a round of pilot projects were funded to build partnerships across universities and across disciplines.
As a trans-disciplinary concept, the Center for Nuclear Femtography (CNF) does not just target Virginia Physicists: such collaborations are made from experts all across the country and the world, including computer scientists, statisticians, mathematicians, and mechanical engineers to name a few. ARC faculty Nicholas Polys and Srijith Rajamohan are Co-PIs on two of these CNF pilot projects: “Visualizing Femtoscale Dynamics” and “Next-generation Visual Analysis Workspace for Multidimensional Nuclear Femtography Data”. Phase One is completing with several exchange visits, meetings and seminars, and a first set of deliverables (public soon).
