Continual learning in real-world scenarios is a major challenge. A general
continual learning model should have a constant memory size and no predefined
task boundaries, as is the case in semi-supervised Video Object Segmentation
(VOS), where continual learning challenges particularly present themselves in
working on long video sequences. In this article, we first formulate the
problem of semi-supervised VOS, specifically online VOS, as a continual
learning problem, and then secondly provide a public VOS dataset, CLVOS23,
focusing on continual learning. Finally, we propose and implement a
regularization-based continual learning approach on LWL, an existing online VOS
baseline, to demonstrate the efficacy of continual learning when applied to
online VOS and to establish a CLVOS23 baseline. We apply the proposed baseline
to the Long Videos dataset as well as to two short video VOS datasets, DAVIS16
and DAVIS17. To the best of our knowledge, this is the first time that VOS has
been defined and addressed as a continual learning problem.

本文提出了一个基于正则化的持续学习方法用于解决在线视频对象分割问题（VOS），取得了很好的效果，同时建立了一个基准公共数据集 CLVOS23。这是首次将 VOS 作为一个持续学习问题来定义和解决。
