Felde, I. Soltys, M. Havryliak, A. Motrych, Yu. Ushenko, V. Dvorzhak, O. Liniuchev // Технологія і техніка друкарства : збірник наукових праць. – 2022. – Вип. 3(77). – С. 47-53. – Бібліогр.: 10 назв.2077-7264https://ela.kpi.ua/handle/123456789/55475The article presents the basics of the method of correlation spatial-frequency filtering of maps of phase distributions of polyethylene films. Using the method of statistical analysis of the structure of spatial-frequency filtered polarization mapsof polymer films, a set of methods and criteria for diagnosingchanges in the birefringence of packaging materials has beensubstantiated and tested.enприкладне програмуванняобробка графічної інформаціїстандартизаціяполіграфіяпакувальні матеріалиматеріалознавствоprogramming methodgraphic information processingstandardizationpublishingpackaging materialsmaterials scienceTechnology of protection and control of printed products using application programs of digital introscopyArticleС. 47-53https://doi.org/10.20535/2077-7264.3(77).2022.274220655:535.361; 535.555
