Hybrid-S2S: Video Object Segmentation with Recurrent Networks and Correspondence Matching

1 code implementation10 Oct 2020 Fatemeh Azimi, Stanislav Frolov, Federico Raue, Joern Hees, Andreas Dengel

In this work, we study an RNN-based architecture and address some of these issues by proposing a hybrid sequence-to-sequence architecture named HS2S, utilizing a dual mask propagation strategy that allows incorporating the information obtained from correspondence matching.
