基于边缘和目标双向交互的伪装物分割网络

Bidirectional and interactive boundary-object network for camouflaged object segmentation

  • 摘要: 由于伪装物在颜色、纹理或模式上与其周围环境具有较高的相似度,因此伪装物边缘难以检测。现有的伪装物分割网络通常采用直接引入边缘检测任务作为辅助,提高网络对于伪装物微小结构和细节的检测能力。然而,边缘检测任务得到的目标轮廓信息时常含有不准确甚至是错误信息,直接将其与不同层级的目标特征整合并不是最优方案。为解决这一问题,本文提出一种边缘和目标双向交互网络,采用双向空间注意力引导模块、双向特征补充模块和特征协同校准模块,探索边缘特征与目标特征之间的互补性,以交互学习的方式逐步校正自身特征错误,从而实现更加精确的伪装物检测。模型在4个常用的公开数据集上与现有主流算法进行比较,实验结果表明所提模型能够有效提高伪装物分割精度。

     

    Abstract: Due to the high similarity between the camouflage objects and their surrounding environment in colors, textures, or patterns, it is quite difficult for the networks to identify the indistinguishable boundaries. Recent camouflaged object segmentation models usually directly introduce boundary detection task as supplement to enhance the detection ability of subtle structures and details. However, such predicted boundaries are often inaccurate or even incorrect. It is not an optimal solution to directly integrate the predicted boundaries at early stage with the object features at different levels for precise segmentation. To address this problem, we propose a bidirectional edge object interaction network, which consists of the bidirectional spatial attention guidance module, the bidirectional feature complementation module, and feature collaborative calibration module. Our proposed network explores the complementary information between the boundary features and the object features, and gradually corrects the errors in an interactive learning manner, thereby achieving more accurate predictions. We conduct extensive experiments on four widely used benchmarks and compare with several state-of-the-arts methods. The experimental results demonstrate the effectiveness and superiority of our network.
