About

Supun Samarasekera is a researcher whose work sits at the dynamic intersection of computer vision, robotics, and autonomous navigation. His research has made significant contributions to spatial perception systems, with a particular focus on visual odometry, multi-sensor fusion, LIDAR-based scene understanding, and robot localization. Among his most influential contributions is his work on building segmentation for densely built urban environments using aerial LIDAR data (2008, 70 citations), which demonstrated that sparse 3D point clouds could reliably parse complex cityscapes. His landmark-matching approach to visual odometry achieved a tenfold improvement in localization accuracy over existing methods (2007, 42 citations), pushing precision to centimeter-level over hundreds of meters traveled — a breakthrough for wearable and robotic systems alike. His plug-and-play factor graph framework for multi-sensor navigation (2014, 62 citations) further advanced real-time robot autonomy in GPS-denied environments. Samarasekera has also explored deep learning-driven visual navigation through semantic transformers (2021) and obstacle detection using graph traversal algorithms applicable across structured and unstructured terrains. His body of work reflects a sustained commitment to building robust, real-world perception systems that bridge the gap between theoretical computer vision and deployable autonomous platforms.
