Christopher Funk, Ph.D., is an R&D engineer on Kitware’s Computer Vision Team located in Arlington, Virginia. He has experience working in multiple modalities, including image, video, remote sensing, motion capture, foot pressure, and medical data (e.g. electroencephalogram, or EEG).
Chris is primarily involved in computer vision/machine learning projects. He leads the two Defense Advanced Research Projects Agency (DARPA) projects, Learning with Less Labels and SAIL-ON Novelty Detection. For the Learning with Less Labels project, he led the creation of a unified framework for image classification, object recognition, and machine translation that integrates with the program’s test and evaluation. The framework has been generalized to multiple projects, now called Tinker, with a focus on simplifying researchers’ integration, ease of running multiple experiments, and moving to production. It has also become the primary framework for SAIL-ON.
Chris is also actively involved in writing proposals, including the successful DARPA SAFE-SiM proposal worth $1.2M in Phase 1 and the National Institutes of Health (NIH) Medical Image Quality Assessment (MIQA) proposal worth $1.6M.
In 2017, Chris helped run the Conference on Computer Vision and Pattern Recognition (CVPR). In the same year, he also helped run the symmetry competition workshop at the International Conference on Computer Vision (ICCV). His work has been published in CVPR and ICCV proceedings. More recently, he also created the official visualization for finding papers at CVPR 2020 and 2021.
While working on his Ph.D., Chris was a teaching assistant for computer vision, pattern recognition and machine learning, computer graphics, and computational symmetry courses. He also worked with machine learning tasks, such as developing the first deep learning-based reflection and rotation symmetry detection approaches. These approaches mimicked human symmetry perception in a real-world, unconstrained setting. He also developed the symmetry dataset by creating an Amazon Mechanical Turk using Django from scratch.
During this time, Chris also analyzed EEG data to understand how the human brain processes symmetry groups. He discovered a connection between human perception and the mathematical perception of symmetry groups. He also developed the first foot pressure estimation algorithm that uses an image to predict a human’s balance. Chris also gained experience working with many texture detection, transfer, and synthesis approaches using classical methods and generative adversarial networks (GANs).
In 2018, Chris received his Ph.D. in computer science from Penn State University. His thesis focused on detecting symmetry in images and how symmetry is detected within the human brain. He received his master’s degree in computer science from Pace University in 2013. During his studies, he took a cognitive approach to computer vision and worked with architectures such as Soar and physics engines like PhysX to learn to predict future object positions. Chris received his bachelor’s degree in government from Franklin & Marshall College in 2010.
