Leveraging Synthetic Data to Learn Video Stabilization Under Adverse Conditions

1 code implementation26 Aug 2022 Abdulrahman Kerim, Washington L. S. Ramos, Leandro Soriano Marcolino, Erickson R. Nascimento, Richard Jiang

In this paper, we propose a synthetic-aware adverse weather robust algorithm for video stabilization that does not require real data and can be trained only on synthetic data.

Straight to the Point: Fast-forwarding Videos via Reinforcement Learning Using Textual Data

1 code implementation CVPR 2020 Washington Ramos, Michel Silva, Edson Araujo, Leandro Soriano Marcolino, Erickson Nascimento

The rapid increase in the amount of published visual data and the limited time of users bring the demand for processing untrimmed videos to produce shorter versions that convey the same information.
