SST: Single-Stream Temporal Action Proposals

Welcome to the official repo for SST: Single-Stream Temporal Action Proposals!

SST is an efficient model for generating temporal action proposals in untrimmed videos. Analogous to object proposals for images, temporal action proposals provide the temporal bounds in videos where potential actions of interest may lie.
