2021 – 2022 Research Highlights

Computational Understanding of Visual Spacetime

Vision-based systems are a central research topic in computing, robotics, and artificial intelligence. This prominence arises as current trends in automotive, consumer and home technology (e.g., Waymo, Amazon Go, Apple HomePod) are leveraging video data to understand how it is possible to understand and react to the environment. Moreover, interesting scientific questions arise as we seek to understand how it is possible to recover detailed information about the world from a mere captured video. My research targets the underpinning theoretical and engineering principles of video understanding.

Some highlights of the past year include development of a theoretical explanation for why ConvNets learn oriented bandpass filters (Hadji & Wildes 2020), development of a novel approach and state-of-the art algorithms for action prediction in videos (Zhao & Wildes 2020) and development of a novel approach and state-of-the-art algorithms for image denoising (Su, Cheung, Wildes and Lin 2020).
