About

Lee Clement is a robotics and computer vision researcher whose work focuses on visual localization, autonomous navigation, and appearance-invariant perception — challenges at the heart of making robots reliably navigate real-world environments. His research addresses one of the field's most persistent problems: enabling autonomous systems to accurately localize and repeat traversed routes despite dramatic changes in lighting and environmental conditions. Clement's most recognized contribution, "How to Train a CAT" (2018, 26 citations), introduced a novel deep learning approach for learning canonical appearance transformations, allowing direct visual localization to remain robust under significant illumination change — a critical hurdle for real-world deployment. His complementary work on monocular Visual Teach and Repeat (VT&R) demonstrated that capable autonomous navigation need not rely on expensive 3D sensors like stereo cameras; by leveraging local ground planarity and color-constant imagery, he showed monocular systems could achieve competitive accuracy (24 and 11 citations respectively). His 2017 work further refined stereo visual odometry through illumination estimation, reflecting a consistent research thread around perception under adverse conditions. Together, these contributions have meaningfully advanced the accessibility and robustness of vision-based autonomous systems, making Clement a notable voice in practical mobile robotics research.
