Title: | Image processing based quality control of coated paper folding | Authors: | Pal, Magdolna Novaković, Đorđe Dedijer, Sandra Koltai L. Jurič, Ivana Vladić, Gojko Kašiković, Nemanja |
Issue Date: | 1-Mar-2017 | Journal: | Measurement: Journal of the International Measurement Confederation | Abstract: | © 2016 Elsevier Ltd During the folding process substrates are exposed to high-localized stresses, which in the case of coated papers and boards, can lead to decreased aesthetic features or complete loss of functionality. Production efficiency of the folding process could be improved by an automated, computer vision-based inspection system. For such a task, different existing computer-aided fold-crack evaluation approaches were analyzed. A detailed research was conducted to propose an image processing based fold cracking assessment via finding optimal sample preparation and digitization techniques and developing an algorithm for the digital image analysis and feature extraction. The analysis of the applicability of different sample preparation and digitization parameters, as well as the proposed digital image feature, was done by correlation evaluation, one-way analysis of variance (ANOVA) and corresponding post hoc tests. The results indicated that the developed algorithm fulfils the set requirements and the proposed feature of digitized samples faithfully describes the analyzed fold-cracks. | URI: | https://open.uns.ac.rs/handle/123456789/3345 | ISSN: | 2632241 | DOI: | 10.1016/j.measurement.2016.12.033 |
