They rely on a collection of static images capturing sparkle properties of pigment flakes. However, visual characteristics of pigment flakes are highly correlated to their material properties and their orientations in coating layers. Thus, while two effect coatings can exhibit similar static sparkle behavior, their dynamic sparkle behavior may be very distinct. In this paper, we analyzed the perception of static and dynamic sparkle using two psychophysical studies on 38 effect coatings and 31 human subjects. First, we have shown a good agreement between the perception of sparkle in real specimens and in photographs. Second, we observed significant differences in perceived static and dynamic sparkle. Our results demonstrate a need for a multiangle recording of sparkle when assessing effect pigment visual characteristics. cav_un_auth*0386524 International Conference on Signal-Image Technology & Internet-Based Systems 2019 /15./ 20191126 20191129 Sorrento IT BD 20000 20200 20201 2020 3 4 A sml 4as 20241106135807.6 PR RVO:67985556 http://hdl.handle.net/11104/0304162 S IEEE COPYRIGHT AND CONSENT FORM 20191029 2019 Soubory v repozitáři: filip-0519062-CopyrightReceipt.pdf SCOPUS PUBMED WOS PDF 4 MB cav_un_epca*0519061 The 15th International Conference on Signal Image Technology & Internet Based Systems, SITIS 2019 978-1-7281-5686-6 732 737 Piscataway IEEE 2019 340 Kokou Yetongnon 340 Dipanda Albert 340 Sanniti di Baja Gabriella 340 Gallo Luigi 340 Chbeir Richard
