家电行业需要一种可靠的方法来评估纺织材料中的皱纹。这种方法对于评估新设计的滚筒式干燥机的性能是必要的。本文描述了一种基于亮度图像数字分析的皱纹分级客观评价系统。该系统能够使用为主观评估而设计的传统检查亭来评估真实服装的褶皱。因此，客观评价皱纹的结果可以与历史记录进行比较。模拟并讨论了光亮度与皱纹三维特征的关系。基于这一分析，我们提出了一种由两个描述符支持的方法，该描述符与训练有素的评价者所欣赏的皱纹特征密切相关。该设计结合了滤波算法，消除了波动和照明不均匀的影响。由重复性和再现性研究证明，客观的皱纹评估与人类专家和稳健的性能具有高度的相关性。
The appliance industry requires a reliable method for wrinkle evaluation in textile materials. This method is necessary to assess the performance of new designs of tumble dryers. In this paper, we describe an objective evaluation system for wrinkle appearance grading based on the digital analysis of luminance images. The system is capable of evaluating wrinkles in real garments using the legacy inspection booth designed for subjective evaluation. Therefore, the results from the objective evaluation of wrinkles can be compared to the historical records. The dependence of luminance on the three-dimensional characteristics of the wrinkles is modeled and discussed. Based on this analysis, we propose a method supported by two descriptors closely related with the wrinkle characteristics as appreciated by trained evaluators. The design incorporates filtering algorithms that eliminate the influence of undulations and the non-uniform illumination. The objective wrinkle evaluation showed high correlation with human experts and robust performance, as demonstrated by the repeatability and reproducibility study.
