Video propagation networks

V Jampani, R Gadde, PV Gehler - Proceedings of the IEEE …, 2017 - openaccess.thecvf.com
We propose a technique that propagates information forward through video data. The
method is conceptually simple and can be applied to tasks that require the propagation of …

Semantic video cnns through representation warping

R Gadde, V Jampani, PV Gehler - Proceedings of the IEEE …, 2017 - openaccess.thecvf.com
