Pappas\, PhD\n\nElectrical and Computer Engineering\n\nNorthwestern University\n\nAbstract: We review recent progress in visual texture analysis from structural texture simila rity metrics to the extraction of material properties. We then investigate data-driven texture modeling via analysis and synthesis with generative a dversarial networks. For network training and testing\, we have compiled a diverse set of spatially homogeneous textures\, ranging from stochastic t o regular. We adopt StyleGAN3 for synthesis and demonstrate that it produc es diverse textures beyond those represented in the training data. For tex ture analysis\, we propose GAN inversion using a novel latent domain recon struction consistency criterion for synthesized textures\, and iterative r efinement with a sliced Wasserstein loss for real-world textures. We propo se perceptual procedures for evaluating network capabilities\, exploring t he global and local behavior of latent space trajectories\, and comparing with existing texture analysis-synthesis techniques.\n\nBio: Thrasos Pappa s received the Ph.D. degree in electrical engineering and computer science from MIT in 1987. From 1987 until 1999\, he was a Member of the Technical Staff at Bell Laboratories\, Murray Hill\, NJ. He joined the ECE Departme nt at Northwestern in 1999. His research interests are in human perception and electronic media\, including image analysis\, quality and compression \, content-based retrieval\, and tactile and multimodal interfaces. Prof. Pappas is a Fellow of the IEEE\, SPIE and IS&T. He has served as Vice Pres ident-Publications (2015-17) and member of the Board of Governors (2004-07 ) of the Signal Processing Society of IEEE\, Editor-in-Chief of the IEEE T ransactions on Image Processing (2010-12)\, and technical program co-chair of ICIP-01 and ICIP-09. He has also served as co-chair of the SPIE/IS&T C onference on Human Vision and Electronic Imaging (1997-2018). He is curren tly one of the two founding Editors-in-Chief of the IS&T Journal of Percep tual Imaging.\n\nFaculty Host: Dr. Enis Cetin (aecyy@uic.edu)\n\nSpeaker(s ): \, Prof. Thrasyvoulos (Thrasos) N.
