图像语义分割方法研究进展

Recent Progress in Semantic Image Segmentation

图像语义分割任务是将图像的每个像素分类到每一个实例中,每个实例对应一个类。该任务是场景理解概念的一部分,由于深度学习的图像语义分割方法能更好地解释图像的全局上下文,越来越受到计算机视觉和机器学习研究者的关注,并广泛应用于室内导航、自动驾驶,甚至虚拟或增强现实系统等领域。本文介绍图像语义分割的术语的概念,回顾传统和现有的深度学习方法,强调了它们在该领域的贡献和意义,以及语义分割算法的评价指标与常用数据集,最后,我们对当前语义图像分割任务中存在的一些问题进行讨论,并提出相关解决方法和研究展望。

The semantic image segmentation task consists of classifying each pixel of an image into an instance, where each instance corresponds to a class. This task is a part of the concept of scene understanding or better explaining the global context of an image. Image semantic segmentation is more and more being of interest for computer vision and machine learning researchers. Many applications on the rise need accurate and efficient segmentation mechanisms: indoor navigation, autonomous driving, and even virtual or augmented reality systems to name a few. This paper provides the concept of image semantic segmentation terms, and reviews traditional and existing deep learning methods with emphasizing their contributions and significance in this field, as well as the evaluation indicators of semantic segmentation algorithms and commonly used datasets. At last, we discuss some problems in current semantic image segmentation tasks, and propose relevant solutions and research prospects.
