摘要:

提出了一种交互式视频对象分割算法,该算法以查询对象上的涂鸦注释为输入。我们开发了一个深度神经网络,它由注释网络(A-Net)和传输网络(T-Net)组成。首先,给定用户在帧上的涂鸦,A-Net基于编码器-解码器架构产生分割结果。其次,T-Net通过全局和局部传输模块将分割结果双向传输到其他帧。全局传送模块将注释帧中的分割信息传送到目标帧,而局部传送模块将时间上相邻的帧中的分割信息传播到目标帧。通过交替应用A-Net和T-Net,用户可以以最小的努力获得期望的分割结果。我们训练整个网络分为两个阶段,通过模拟用户涂鸦和采用辅助损失。实验结果表明,提出的交互式视频对象分割算法优于国家的最先进的传统算法。代码和模型可在https://github.com/yuk6heo/IVOS-ATNet上获得。

英文摘要:

An interactive video object segmentation algorithm, which takes scribble annotations on query objects as input, is proposed in this paper. We develop a deep neural network, which consists of the annotation network (A-Net) and the transfer network (T-Net). First, given user scribbles on a frame, A-Net yields a segmentation result based on the encoder-decoder architecture. Second, T-Net transfers the segmentation result bidirectionally to the other frames, by employing the global and local transfer modules. The global transfer module conveys the segmentation information in an annotated frame to a target frame, while the local transfer module propagates the segmentation information in a temporally adjacent frame to the target frame. By applying A-Net and T-Net alternately, a user can obtain desired segmentation results with minimal efforts. We train the entire network in two stages, by emulating user scribbles and employing an auxiliary loss. Experimental results demonstrate that the proposed interactive video object segmentation algorithm outperforms the state-of-the-art conventional algorithms.
