Learning to Recommend Frame for Interactive Video Object Segmentation in the Wild
[article]
2021
arXiv
pre-print
Preserved Fulltext
Other Versions
This paper proposes a framework for the interactive video object segmentation (VOS) in the wild where users can choose some frames for annotations iteratively. ...
Thus, we formulate the frame selection problem in the interactive VOS as a Markov Decision Process, where an agent is learned to recommend the frame under a deep reinforcement learning framework. ...
