Learning Spatial Features from Audio-Visual Correspondence in Egocentric Videos

Sagnik Majumder, Ziad Al-Halah, Kristen Grauman

We propose a self-supervised method for learning representations based on spatial audio-visual correspondences in egocentric videos. Our method uses a masked auto-encoding framewor…

SpotEM: Efficient Video Search for Episodic Memory

Santhosh Kumar Ramakrishnan, Ziad Al-Halah, Kristen Grauman

The goal in episodic memory (EM) is to search a long egocentric video to answer a natural language query (e.g., "where did I leave my purse?"). Existing EM methods exhaustively ext…
