Thomas A. FunkhouserLearning Structured Implicit Shape Representations
AbstractThere has recently been an explosion of research on learning implicit shape representations, which has produced very impressive results for shape reconstruction, synthesis, and rendering using implicit functions represented purely by deep networks. In this talk, I will discuss ways to combine these deep implicit functions with traditional 3D shape representations—specifically using voxels, wavelets, and metaballs as a substrate for the implicit functions. I hope to demonstrate that the resulting hybrid representations (combining traditional explicit geometric decompositions with recent deep implicit functions) can achieve better accuracy, scale, and interpretability for multiple applications.
Thomas is the David M. Siegel Professor of Computer Science at Princeton University, transferring to emeritus status in 2019. He is also a senior researcher at Google Research. Thomas has been at the forefront of research of many sub-fields within geometry processing, contributing tremendously to the naissance of shape retrieval. Relevant to this workshop, Thomas has also helped produce many valuable benchmarking datasets for researchers. With over 150 publications to date, Thomas' significant contributions to the field have been recognised by the community—leading to his recent induction into the ACM SIGGRAPH Academy in 2018. Thomas was also elected to become an ACM fellow in that same year.
Recently, Thomas' research interests have included scene understanding, scene reconstruction, robotics, implicit 3D shape representation, human pose prediction, and shape modelling.
Alexander M. BronsteinLearning to See in the Data Age
AbstractRecent spectacular advances in machine learning techniques allow solving complex computer vision tasks—all the way down to vision-based decision making. However, the input image itself is still produced by imaging systems that were built to produce human-intelligible pictures that are not necessarily optimal for the end task. In this talk, I will try to entertain ourselves with the idea of including the camera hardware (optics and electronics) among the learnable degrees of freedom. I will show examples from optical, ultrasound, and magnetic resonance imaging demonstrating that simultaneously learning the "software" and the "hardware" parts of an imaging system is beneficial for the end task.
