Zusammenfassung Der Naumburger Dom zählt zu den bedeutendsten Kulturdenkmälern des Hochmittelalters. Da er keine Einnahmen aus der Kirchensteuer erhält, ist der Dom auf touristische Einnahmen angewiesen. Vor diesem Hintergrund steht das Image des Bauwerks im Mittelpunkt des Beitrags. Dieses...

Purpose The purpose of this study is to gather insights into digital consumer behaviour related to Chinese restaurents by examining visual contents on Tripadvisor platform. Design/methodology/approach Using the deep learning approach, this research assessed consumer-posted online content of...

We address the issue of edge detection in Synthetic Aperture Radar imagery. In particular, we propose nonparametric methods for edge detection, and numerically compare them to an alternative method that has been recently proposed in the literature. Our results show that some of the proposed...

We present a model to describe the collective motion of barchan dunes in a field. Our model is able to reproduce the observation that a typical dune stays confined within a stripe. We also obtain some of the pattern structures which resemble those observed from aerial photos which we do analyse...

This work proposes to obtain novel fractal descriptors from gray-level texture images by combining information from interior and boundary measures of the Minkowski dilation applied to the texture surface. At first, the image is converted into a surface where the height of each point is the gray...

The medial axis and the inner parallel body of a set C are different formal translations for the notions of the “central core” and the “bulk”, respectively, of C. On the basis of their applications in image analysis, both notions (and especially the first one) have been extensively...

In this work we deal with the problem of estimating the support S of a probability distribution under shape restrictions. The shape restriction we deal with is an extension of the notion of convexity named α-convexity. Instead of assuming, as in the convex case, the existence of a separating...

An entropy-based image segmentation approach is introduced and applied to color images obtained from Google Earth. Segmentation refers to the process of partitioning a digital image in order to locate different objects and regions of interest. The application to satellite images paves the way to...
