提出全双工策略网络FSNet,通过关系交叉注意力模块和双向净化模块实现运动与表观特征的双向传播与净化,在视频目标分割与显著目标检测任务中取得优异性能。

摘要:

先前的视频目标分割方法主要侧重于在表观和运动之间使用单工解决方案,限制了这两种线索之间及内部的特征协作效率。在这项工作中,我们研究了一种新颖且高效的全双工策略网络(FSNet)来解决这一问题,通过在融合和解码阶段利用跨模态特征时,考虑运动和表观之间更好的相互约束方案。具体而言,我们引入了关系交叉注意力模块(RCAM)以实现跨嵌入子空间的双向消息传播。为了提高模型的鲁棒性并更新来自时空嵌入的不一致特征,我们在RCAM之后采用了双向净化模块(BPM)。在五个流行基准上的大量实验表明,我们的FSNet对各种具有挑战性的场景(例如,运动模糊、遮挡)具有鲁棒性,并且在视频目标分割和视频显著目标检测任务中都取得了优于现有前沿方法的性能。该项目公开于:https://dpfan.net/FSNet。

英文摘要:

Previous video object segmentation approaches mainly focus on using simplex solutions between appearance and motion, limiting feature collaboration efficiency among and across these two cues. In this work, we study a novel and efficient full-duplex strategy network (FSNet) to address this issue, by considering a better mutual restraint scheme between motion and appearance in exploiting the cross-modal features from the fusion and decoding stage. Specifically, we introduce the relational cross-attention module (RCAM) to achieve bidirectional message propagation across embedding sub-spaces. To improve the model's robustness and update the inconsistent features from the spatial-temporal embeddings, we adopt the bidirectional purification module (BPM) after the RCAM. Extensive experiments on five popular benchmarks show that our FSNet is robust to various challenging scenarios (e.g., motion blur, occlusion) and achieves favourable performance against existing cutting-edges both in the video object segmentation and video salient object detection tasks. The project is publicly available at: https://dpfan.net/FSNet.
