key words: wall paintings, rocky hewn churches, Cappadocia (Turkey), pigments, Raman spectroscopy, Fourier transform infrared spectrometry This paper presents the results of the analysis on the rock hewn wall paintings of eleven churches in Cappadocia, Turkey. A large group of churches in the region of Nevşehir were analysed in order to increase the database of materials and techniques of medie...

Paintings are of great value of art, especially in the era of early modern Europe, a lot of talented painters emerged and gave the world a great amount of fortune. It was probably not too much later that art forgeries emerged after the art value has been discovered [1]. It becomes obviously important for art experts to identify various paintings of different painters. The traditional ways of do...

While literature often tries to impute mathematical constants into art, this large-scale study (11 databases of paintings and photos, around 200.000 items) shows a different truth. The analysis, consisting of the width/height propor‐ tions, shows a value of rarely if ever one (square) and with majority of images having a proportion larger than one, but less than e.g. the golden ratio. Further‐ ...

With the vast expansion of digital contemporary painting collections, automatic theme stylization has grown in demand in both academic and commercial fields. The recent interest in deep neural networks has provided powerful visual features that achieve state-of-the-art results in various visual classification tasks. In this work, we examine the perceptiveness of these features in identifying ar...

In this paper, a feature-detecting algorithm to identify paintings from mobile phone camera images is presented. The algorithm is capable of identifying paintings from noisy camera-phone images. Even with typical blurring, rotation, and a small amount of perspective distortion that would occur in a controlled museum setting, by training on a set of standard painting images, the paintings can be...

Discovering hidden details in historical paintings, such as pentimenti, can help reveal historical influences and changing intentions of an artist. Top-down photographs of visible light historical paintings do not capture much of the finer surface detail on the object being photographed. We present a technique using only visible light photography with a specially constructed octagonal reflector...

Preharvest conditions, including photoperiod and irrigation regime, affect the keeping quality of long stem roses (Rosa x hybrida). Rose plants cultivar ‘Charming Black’ were subjected to four different treatments investigate how nocturnal supplemental lighting regimes influence post-harvest performance. Vase life, ornamental quality, water balance, petal color, vacuolar pH, soluble sugar conte...
