Measuring and evaluating directional textures and using them in visual discovery
No full textThis dissertation focuses on three aspects of directional textures. The first aspect is the development of a new directional texture-based visualization technique to address challenges in visualizing multivariate data in a single display. The technique uses a multi level Markov Random Field-based texture synthesis to progressively generate a visualization that encodes data variables using various texture features, especially texture direction. Since texture directionality has not been used extensively in visualization, this technique provides a new visual cue to display additional data variable in a single display. Evaluations of the new texture-based visualization technique are also presented. The second aspect is the development of a new texture directionality measure to determine directional status of textures. The new texture directionality measure considers both local and global characteristics of textures. A comprehensive comparison study of the new measure with existing measures is also presented. The comparison is the first such study that considers all textures from the Brodatz texture database. The third aspect is applications of the new texture directionality measure to several classification problems

High Performance and Disruptive Computing in Remote Sensing: The Third Edition of the School Organized by the HDCRS Working Group of the GRSS Earth Science Informatics Technical Committee
No full textFrom May 29 to June 1, 2023, the University of Iceland in Reykjavik hosted the third "High Performance and Disruptive Computing in Remote Sensing" school. Organized by the HDCRS Working Group of the GRSS Earth Science Informatics Technical Committee (ESI TC), the event aimed to educate attendees on the latest advancements in parallel and scalable computing algorithms and technologies as they pertain to remote sensing. The curriculum spanned four key topics and integrated theoretical knowledge with practical exercises. With over 100 global registrations, 30 individuals were chosen for the in-person event in Reykjavik, based on a rigorous selection process emphasizing diversity, experience, and skills. All sessions have been made accessible on the GRSS YouTube channel, and the event saw participants from 15 countries across 4 continents
