Abstract
- • Coarse-to-fine segmentation. The proposed interaction of supervised and unsupervised models can realize fine-grained foreground segmentation. • Unsupervised background model updates. The unsupervised statistical background model can update and avoid deadlock by using segmented masks as external selectiveupdating cues. • This method is more flexible than deep learning-based methods that depend on scenespecific training. Compared with unsupervised models, it reduces the number of training samples and utilizes training datasets with no human intervention. In this paper 1 1 Dong Liang, Bin Kang and Xinyu Liu contributed equally to this work. , we investigate cross-scene video foreground segmentation via supervised and unsupervised model communication. Traditional unsupervised background subtraction methods often face the challenging problem of updating the statistical background model online. In contrast, supervised foreground segmentation methods, such as those that are based on deep learning, rely on large amounts of training data, thereby limiting their cross-scene performance. Our method leverages segmented masks from a cross-scene trained deep model (spatio-temporal attention model (STAM), pyramid scene parsing network (PSPNet), or DeepLabV3+) to seed online updates for the statistical background model (CPB), thereby refining the foreground segmentation. More flexible than methods that require scene-specific training and more data-efficient than unsupervised models, our method outperforms state-of-the-art approaches on CDNet2014, WallFlower, and LIMU according to our experimental results. The proposed framework can be integrated into a video surveillance system in a plug-and-play form to realize cross-scene foreground segmentation. [ABSTRACT FROM AUTHOR]
