摘要:

全面的场景理解是实现机器人自主性的关键使能因素。语义分割是场景理解的关键任务之一,对自动驾驶、家庭服务机器人、最后一公里配送等众多机器人应用至关重要。语义分割是一种密集预测任务,旨在提供一种场景表示,其中图像的每个像素都被赋予一个语义类别标签。因此,语义分割考虑完整的场景上下文,融合所有场景元素(包括背景)的物体类别、位置和形状信息。多年来,人们提出了大量用于语义分割的算法。然而,近年来深度学习的发展,加上计算能力的提升和大规模标注数据集的可用性,推动了语义分割的显著进步。在本章中,我们介绍语义分割任务,并阐述多年来为应对该任务而提出的深度学习技术。我们首先定义语义分割任务,并将其与其他密切相关的场景理解问题进行对比。我们详细介绍了用于语义分割的不同算法和架构,以及常用的损失函数。此外,我们概述了语义分割中使用的数据集、基准和评估指标。最后,我们讨论了该领域进一步研究所面临的挑战与机遇。

英文摘要:

Comprehensive scene understanding is a critical enabler of robot autonomy. Semantic segmentation is one of the key scene understanding tasks which is pivotal for several robotics applications including autonomous driving, domestic service robotics, last mile delivery, amongst many others. Semantic segmentation is a dense prediction task that aims to provide a scene representation in which each pixel of an image is assigned a semantic class label. Therefore, semantic segmentation considers the full scene context, incorporating the object category, location, and shape of all the scene elements, including the background. Numerous algorithms have been proposed for semantic segmentation over the years. However, the recent advances in deep learning combined with the boost in the computational capacity and the availability of large-scale labeled datasets have led to significant advances in semantic segmentation. In this chapter, we introduce the task of semantic segmentation and present the deep learning techniques that have been proposed to address this task over the years. We first define the task of semantic segmentation and contrast it with other closely related scene understanding problems. We detail different algorithms and architectures for semantic segmentation and the commonly employed loss functions. Furthermore, we present an overview of datasets, benchmarks, and metrics that are used in semantic segmentation. We conclude the chapter with a discussion of challenges and opportunities for further research in this area.
