摘要:

由于裂纹的背景、形状、颜色和大小等都不相同,因此表面裂纹的分割是一项具有挑战性的计算机视觉任务。在这项工作中,我们提出了优化的深度编码器-解码器方法,包括一系列技术,这些技术可以提高裂缝分割性能。具体来说,我们提出了一个基于编码器-解码器的深度学习架构的解码器部分,用于语义分割,并研究其组件以提高性能。我们还研究了不同编码器策略的使用,并引入了一个数据增强策略来增加可用的训练数据量。我们的方法的性能评估进行了四个公开可用的裂纹分割数据集。此外,我们将两种技术引入表面裂纹分割领域,以前没有使用过:使用测试时间增强生成结果,并在多个训练运行中执行统计结果分析。前一种方法通常会产生更高的性能结果,而后者允许方法结果的可重复性和可代表性更好。使用上述策略与我们提出的编码器-解码器架构,我们能够在所有数据集中实现新的最先进的结果。

英文摘要:

Surface crack segmentation poses a challenging computer vision task as background, shape, colour and size of cracks vary. In this work we propose optimized deep encoder-decoder methods consisting of a combination of techniques which yield an increase in crack segmentation performance. Specifically we propose a decoder-part for an encoder-decoder based deep learning architecture for semantic segmentation and study its components to achieve increased performance. We also examine the use of different encoder strategies and introduce a data augmentation policy to increase the amount of available training data. The performance evaluation of our method is carried out on four publicly available crack segmentation datasets. Additionally, we introduce two techniques into the field of surface crack segmentation, previously not used there: Generating results using test-time-augmentation and performing a statistical result analysis over multiple training runs. The former approach generally yields increased performance results, whereas the latter allows for more reproducible and better representability of a methods results. Using those aforementioned strategies with our proposed encoder-decoder architecture we are able to achieve new state of the art results in all datasets.
