Di Cicco, F. (author), van Zuijlen, M.J.P. (author), Wijntjes, M.W.A. (author), Pont, S.C. (author)Dutch 17th century painters were masters in depicting materials and their properties in a convincing way. Here, we studied the perception of the material signatures and key image features of diļ¬erent depicted fabrics, like satin and velvet. We also tested whether the perception of fabrics depicted in paintings related to local or global cues,...journal article 2021

van Zuijlen, M.J.P. (author), Pont, S.C. (author), Wijntjes, M.W.A. (author)Painters are masters of depiction and have learned to evoke a clear perception of materials and material attributes in a natural, three-dimensional setting, with complex lighting conditions. Furthermore, painters are not constrained by reality, meaning that they could paint materials without exactly following the laws of nature, while still...journal article 2020

Zhang, F. (author), de Ridder, H. (author), Barla, Pascal (author), Pont, S.C. (author)We previously presented a systematic optics-based canonical approach to test material-lighting interactions in their full natural ecology, combining canonical material and lighting modes. Analyzing the power of the spherical harmonics components of the lighting allowed us to predict the lighting effects on material perception for generic...journal article 2020

Di Cicco, F. (author), Wijntjes, M.W.A. (author), Pont, S.C. (author)To understand the key image features that we use to infer the glossiness of materials, we analyzed the pictorial shortcuts used by 17th century painters to imitate the optical phenomenon of specular reflections when depicting grapes. Gloss perception of painted grapes was determined via a rating experiment. We computed the contrast, blurriness,...journal article 2019
