• Abstract: Considerable unsupervised video object segmentation algorithms based on deep learning have the problem of substantive model parameters and computation, which significantly limits the application of the algorithm in practice. This paper proposes a video object segmentation network based on motion guidance, considerably reducing the number of model parameters and computation and improving the video object segmentation performance. The model comprises a dual-stream network, motion guidance module, and multi-scale progressive fusion module. Specifically, RGB images and optical flow estimation are fed into dual-stream network to extract object appearance features and motion features. Then, the motion guidance module extracts the semantic information from the motion features through local attention, which guides the appearance features to learn rich semantic information. Finally, the multi-scale progressive fusion module obtains the output features at each stage of the dual-stream network. It gradually integrates the deep features into the shallow ones yet improves the edge segmentation effect. In this paper, numerous evaluations are conducted on three standard datasets, and the experimental results prove the superior performance of the proposed method.

  We propose a unified action recognition framework to investigate the dynamic nature of video content. First, when extracting local cues, we generate the spatial-temporal kernels of dynamic-scale to adaptively fit the diverse events. Second, to accurately aggregate these cues into a global video representation, we propose to mine the interactions only among a few selected foreground objects by a Transformer.

It takes two consecutive frames as input and predicts segmentation masks for the background and multiple rigidly moving objects, which are then parameterized by 3D rigid transformations. Our method achieves state-of-the-art performance for rigid motion segmentation on KITTI and Sintel.
