“…This work is one of the most similar to our own and the numerous common factors allowed us to compare some aspects at the very end of the document. In [15] a different approach is shown. Instead of Allen's logic, the authors proposed a method that is similar to a propositional logic grammar for describing events.…”

“…When two sensors collaborate to recognize the same event, it could be not necessary to consider the combination of single results. The proposed grammar is inspired by other multimodal spatio-temporal logic based frameworks [123,15]. A rule is composed by two main sections: the condition and the actuation.…”

Human-computer and multimodal interaction are increasingly used in everyday life. Machines are able to get more from the surrounding world, assisting humans in different application areas. In this context, the correct processing and management of signals provided by the environments is determinant for structuring the data. Different sources and acquisition times can be exploited for improving recognition results. On the basis of these assumptions, we are proposing a multimodal system that exploits Allen's temporal logic combined with a prevision method. The main object is to correlate user's events with system's reactions. After post-elaborating coming data from different signal sources (RGB images, depth maps, sounds, proximity sensors, etc.), the system is managing the correlations between recognition/detection results and events in real-time to create an interactive environment for the user. For increasing the recognition reliability, a predictive model is also associated with the proposed method. The modularity of the system grants a full dynamic development and upgrade with custom modules. Finally, a comparison with other similar systems is shown, underlining the high flexibility and robustness of the proposed event management method. Ringraziamenti Questo percorso di crescita personale ha portato ad interiorizzare conoscenze notevoli in ambito della computer vision e non solo. Devo molto al Prof. Luigi Cinque per questa opportunità offertami. Inoltre, la sua umanità è stata la virtù più rara che abbia trasmesso. Contestualmente, ho avuto il piacere e l'onore di poter lavorare con un gruppo di ricerca tra i migliori d'Italia. Il Visionlab è diventato un punto di riferimento in questi 3 anni e senza Daniele, Cristiano e Marco probabilmente non avrei raggiunto i risultati di oggi. Devo molto anche a loro. Infine, devo fare un ringraziamento speciale a Danilo Avola, colui che ha fornito un supporto determinante alla ricerca dell'intero laboratorio. Una guida, un maestro ed anche un amico.

“…Our conceptual vision to express the notion of 'land-use trajectory' draws partly on the GIScience research on ontologies (Hornsby and Egenhofer 2000, Yuan 2001, Bennett et al 2002, Galton 2004, Grenon and Smith 2004, Worboys 2005, Kuhn 2012). These papers focus on the notions of 'objects', 'events' and 'processes'.…”

Earth observation images are a powerful source of data about changes in our planet. Given the magnitude of global environmental changes taking place, it is important that Earth Science researchers have access to spatiotemporal reasoning tools. One area of particular interest is land-use change. Using data obtained from images, researchers would like to express abstractions such as 'land abandonment', 'forest regrowth', and 'agricultural intensification'. These abstractions are specific types of land-use trajectories, defined as multi-year paths from one land cover into another. Given this need, this paper introduces a spatiotemporal calculus for reasoning about land-use trajectories. Using Allen's interval logic as a basis, we introduce new predicates that express cases of recurrence, conversion and evolution in land-use change. The proposed predicates are sufficient and necessary to express different kinds of land-use trajectories. Users can build expressions that describe how humans modify Earth's terrestrial surface. In this way, scientists can better understand the environmental and economic effects of land-use change. ARTICLE HISTORY

“…The accessibility relations of modal operators have also been directly employed as spatial relations in modal logics (Cohn, 1993;Lutz & Wolter, 2004) and multi-modal logics (Bennett, et al, 2002). More generally, every spatial logic is just a logic interpreted over spatial, i.e.…”
