Abstract

In this paper we address the issue of photo galleries synchronization, where pictures related to the same event are collected by different users. Existing solutions to address the problem are usually based on unrealistic assumptions, like time consistency across photo galleries, and often heavily rely on heuristics, limiting therefore the applicability to real-world scenarios. We propose a solution that achieves better generalization performance for the synchronization task compared to the available literature. The method is characterized by three stages: at first, deep convolutional neural network features are used to assess the visual similarity among the photos; then, pairs of similar photos are detected across different galleries and used to construct a graph; eventually, a probabilistic graphical model is used to estimate the temporal offset of each pair of galleries, by traversing the minimum spanning tree extracted from this graph. The experimental evaluation is conducted on four publicly available datasets covering different types of events, demonstrating the strength of our proposed method. A thorough discussion of the obtained results is provided for a critical assessment of the quality in synchronization., Comment: ACCEPTED to IEEE Transactions on Multimedia

Abstract

Background: Although long-term management of psoriasis is paramount, this approach is challenging in clinical practice. In the recent PSO-LONG trial, a fixed-dose combination of betamethasone dipropionate (BD) and calcipotriol (Cal) foam applied twice a week on non-consecutive days for 52 weeks (proactive treatment) reduced the risk of relapse. However, the role of Cal/BD foam in the long-term management of psoriasis needs further clarifications. The ProActive Management (PAM) program, a nationwide Italian project, aims at reaching a consensus on the role of proactive management of psoriasis. Methods: A steering committee generated some statements through the nominal group technique (NGT). The statements were voted by an expert panel in an adapted Delphi voting process. Results: Eighteen statements were proposed, and the majority of them (14/18) reached a consensus during the Delphi voting. The need to provide long-term proactive topical treatment to reduce the risk of relapse for the treatment of challenging diseases sites or in patients where phototherapy or systemic therapies are contraindicated/ineffective was widely recognized. A consensus was reached about the possibility to associate the proactive treatment with systemic and biological therapies, without the need for dose intensification, thus favoring a prolonged remission. Moreover, the proactive treatment was recognized as more effective than weekend therapy in increasing time free from relapses. Approaches to improve adherence, on the other hand, need further investigation. Conclusions: The inclusion in guidelines of a proactive strategy among the effective treatment options will be a fundamental step in the evolution of a mild-moderate psoriasis therapeutic approach.

Abstract

Deadwood plays a key role in the functioning and productivity of forest ecosystem and it is an important feature for assessing and monitoring biodiversity. The third Ministerial Conference on the Protection of Forests in Europe (MCPFE) has recognized the importance of this forest component at the European level. More recently the national forest inventories have tried to harmonize the procedures including the quantitative and qualitative measurements of deadwood. This paper reports on the methods and results of Italian National Inventory of Forests and Forest Carbon Sinks (INFC) and compares the deadwood data with the results of other main European inventories and some local studies. In Italy the volume of deadwood (logs, snags and stumps) is on average 8.8 m3 ha-1.

14. Image diversity analysis: context, opinion and bias

Author

Zontone, Pamela, Boato, Giulia, De Natale, F. G. B., De Rosa, Alessia, Barni, Mauro, Piva, Alessandro, Hare, Jonathan, Dupplaw, David, and Lewis, Paul

Abstract

The diffusion of new Internet and web technologies has increased the distribution of different digital content, such as text, sounds, images and videos. In this paper we focus on images and their role in the analysis of diversity. We consider diversity as a concept that takes into account the wide variety of information sources, and their differences in perspective and viewpoint. We describe a number of different dimensions of diversity; in particular, we analyze the dimensions related to image searches and context analysis, emotions conveyed by images and opinion mining, and bias analysis.

Abstract

We address the widely open problem of access control in wireless sensor networks (WSN). Namely, we apply a suitable threshold secret sharing scheme relying on advanced polynomial interpolation theory to design a distributed access control protocol exploiting the natural hierarchical structure of the WSN.
