多尺度上下文信息增强的显著目标检测全卷积网络

Salient Object Detection with Multiscale Context Enhanced Fully Convolutional Network

  • 摘要: 针对目前基于深度学习的显著目标检测算法存在的目标完整性和区域平滑度的不足,基于非局部深度特征提出一种多尺度上下文信息增强的全卷积网络算法,包含多级别特征提取、多尺度上下文特征增强、对比度特征提取和局部-全局信息融合预测4个模块.首先从VGG16模型提取多级别局部特征,利用多尺度上下文实现特征信息增强;然后设计组合的损失函数进行网络训练以学习对比度特征;最后用局部-全局融合的方式实现显著图的预测.与已有算法在ECSSD,HKU-IS和DUT-OMRON数据集上进行实验的结果表明,该算法在复杂场景图像上的鲁棒性更好,对背景噪声具有更有效的抑制作用,得到的显著目标区域更加连续和完整.

     

    Abstract: To tackle the problem of object imperfection and region abruption in existing deep salient object detection algorithms, a multiscale context enhanced fully convolutional network(MCE-FCN) based on non-local deep features(NLDF) is proposed. The network includes four modules which are responsible for multi-level features extraction, multiscale context feature enhancement, contrast feature extraction and local-global fusion. Firstly, multi-level local features are extracted from VGG16 model. Secondly, multiscale context information is exploited to enhance the local features. Then, combined loss function is designed to extract contrast features. Finally, the saliency map is predicted in the local-global fusion way. The proposed algorithm is compared with other algorithms in ECSSD, HKU-IS and DUT-OMRON datasets. Experimental results show that the proposed method is more robust for natural images with complex scenes and has more effective suppression on background noise, and the result salient object regions are more consistent and complete.
