Litany

Dr. Or Litany is a new faculty member in the Department of Computer Science at the Technion – Israel Institute of Technology.

Specializing in artificial intelligence (AI) for computer vision, Or’s work emphasizes the generation, reconstruction, and semantic interpretation of what he terms 4D digital environments, namely, the three spatial dimensions plus time.

As an Azrieli Fellow, Or will push the boundaries of leveraging internet-scale video data in order to analyze and synthesize dynamic 3D objects and scenes. By incorporating the rich spatio-temporal structures present in videos, Or intends to advance the domain of 3D vision. Given the exponential growth in video content, his research posits that utilizing videos for 3D tasks could overcome the complexities of capturing 3D data at scale using specialized equipment. The practical applications of this research are manifold, including detecting and tracking objects of any category in images and videos, recovering the geometric structure of scenes, and generating and editing visual content from partial observations for immersive interaction.

Or received his BSc in physics and mathematics from the Hebrew University under the auspices of the IDF Talpiot program. He subsequently completed his Masters and PhD at Tel Aviv University under the supervision of Prof. Alex Bronstein. He conducted postdoctoral research at Stanford University and Meta AI Research under the guidance of Prof. Leonidas Guibas, developing VoteNet, an innovative technique for 3D object detection in point cloud environments. He also introduced PointContrast, the first large- scale point cloud contrastive representation learning method. He lives in Haifa with his wife, Ayelet, and their three children: Adam, Roni, and Nadav. In his free time, Or enjoys writing and recording music.
