摘要:

本文首次尝试使用图像级类别标签作为监督来学习语义边界检测。我们的方法开始通过估计对象类的粗糙区域引起的注意的图像分类网络。由于边界将位于不同类别的这些区域之间的某个地方,我们的任务被制定为一个多实例学习(MIL)的问题,其中连接两个不同类别的区域的线段上的像素被视为一袋边界候选人。此外,我们设计了一个新的神经网络架构,可以学习估计语义边界可靠,即使不确定的监督MIL策略。我们的网络用于生成训练图像的伪语义边界标签,这些标签又用于训练完全监督模型。使用我们的伪标签训练的最终模型在SBD数据集上实现了出色的性能,它与以前的一些经过更强监督训练的艺术一样具有竞争力。

英文摘要:

This paper presents the first attempt to learn semantic boundary detection using image-level class labels as supervision. Our method starts by estimating coarse areas of object classes through attentions drawn by an image classification network. Since boundaries will locate somewhere between such areas of different classes, our task is formulated as a multiple instance learning (MIL) problem, where pixels on a line segment connecting areas of two different classes are regarded as a bag of boundary candidates. Moreover, we design a new neural network architecture that can learn to estimate semantic boundaries reliably even with uncertain supervision given by the MIL strategy. Our network is used to generate pseudo semantic boundary labels of training images, which are in turn used to train fully supervised models. The final model trained with our pseudo labels achieves an outstanding performance on the SBD dataset, where it is as competitive as some of previous arts trained with stronger supervision.
