摘要:

在本文中,我们解决了弱监督对象定位(WSL)问题,该问题在仅具有图像级注释的数据集上训练检测网络。所提出的方法是建立在这样的观察基础上的:来自训练数据集的建议集是背景、对象部分和对象的集合。采取了几种策略来自适应地消除噪声建议,并为弱标记数据集生成伪对象级注释。采用屏蔽策略增强的多实例学习(MIL)算法来收集特定于类的对象建议,然后利用这些建议来使预训练的分类网络适应检测网络。此外,通过在建议子集优化框架中联合考虑检测分数和建议的重叠率来重新加权来自检测网络的检测结果。最佳建议作为对象级标签,使伪强监督数据集能够用于训练检测网络。因此,我们建立了一个完全自适应的检测网络。对PASCAL VOC 2007和2012数据集的广泛评估表明,与最先进的方法相比,有了显着的改进。

英文摘要:

In this paper, we address the problem of weakly supervised object localization (WSL), which trains a detection network on the dataset with only image-level annotations. The proposed approach is built on the observation that the proposal set from the training dataset is a collection of background, object parts, and objects. Several strategies are taken to adaptively eliminate the noisy proposals and generate pseudo object-level annotations for the weakly labeled dataset. A multiple instance learning (MIL) algorithm enhanced by mask-out strategy is adopted to collect the class-specific object proposals, which are then utilized to adapt a pre-trained classification network to a detection network. In addition, the detection results from the detection network are re-weighted by jointly considering the detection scores and the overlap ratio of proposals in a proposal subset optimization framework. The optimal proposals work as object-level labels that enable a pseudo-strongly supervised dataset for training the detection network. Consequently, we establish a fully adaptive detection network. Extensive evaluations on the PASCAL VOC 2007 and 2012 datasets demonstrate a significant improvement compared with the state-of-the-art methods.
