摘要:

语义分割的目的是对输入图像的每个像素进行分类。考虑到获取密集标签的困难,研究人员最近一直在求助于弱标签来减轻分割的注释负担。然而,现有的工作主要集中在扩大种子的伪标签内的图像的显着区域。在这项工作中,我们提出了一个非显着区域对象挖掘方法弱监督语义分割。我们引入了一个基于图的全局推理单元,以加强分类网络的能力,捕捉不相交和遥远的区域之间的全局关系。这有助于网络激活显著区域之外的对象特征。为了进一步挖掘非显著区域对象,我们提出发挥分割网络的自校正能力。具体来说,提出了一个潜在对象挖掘模块,以降低伪标签的假阴性率。此外,我们提出了一个非显着区域掩蔽模块复杂的图像生成掩蔽的伪标签。我们的非显著区域掩蔽模块有助于进一步发现非显著区域中的对象。在PASCAL VOC数据集上进行的大量实验证明了与当前方法相比最先进的结果。

英文摘要:

Semantic segmentation aims to classify every pixel of an input image. Considering the difficulty of acquiring dense labels, researchers have recently been resorting to weak labels to alleviate the annotation burden of segmentation. However, existing works mainly concentrate on expanding the seed of pseudo labels within the image's salient region. In this work, we propose a non-salient region object mining approach for weakly supervised semantic segmentation. We introduce a graph-based global reasoning unit to strengthen the classification network's ability to capture global relations among disjoint and distant regions. This helps the network activate the object features outside the salient area. To further mine the non-salient region objects, we propose to exert the segmentation network's self-correction ability. Specifically, a potential object mining module is proposed to reduce the false-negative rate in pseudo labels. Moreover, we propose a non-salient region masking module for complex images to generate masked pseudo labels. Our non-salient region masking module helps further discover the objects in the non-salient region. Extensive experiments on the PASCAL VOC dataset demonstrate state-of-the-art results compared to current methods.
