Content-based navigation within virtual museums

Abstract

The ongoing evolution of the Internet has enabled web applications that use real time three-dimensional (3D) graphics and virtual environments. Moreover, in recent years, cultural technology has also flourished notably. Virtual museums represent one significant application that combines culture with modern technologies and the internet, requiring an interdisciplinary approach aiming both at dissemination and education. We present our approach to enhance virtual museums by incorporating content-based retrieval that refers to 3D objects. In this context, a virtual visitor is able to navigate within the museum, examine the exhibited artifacts and perform queries-byexample in order to locate the position of related artifacts. The retrieval mechanism responds to the visitor's queries by indicating similar artifacts, which are ranked according to their similarity scores. This way, the visitor is able to navigate within a virtual museum not only by means of a virtual walkthrough but also by means of the context.

AI trends in digital humanities research

“…Although virtual exhibitions and museums have a long history, advanced virtual museums research has a signifi cantly shorter history. In the early years, Koutsoudis, et al in 2012, proposed an integration of formerly unconnected technologies, VR, gaming and content-based 3D object retrieval [53]. The proposed system, built on game engine technology, used 3D shape analysis of exhibits and enabled the integration of content-based navigation into the framework of a virtual museum experience, supporting, at the same time, state-ofthe-art visualisations and real-time interactions.…”

A universal method to compare parts from STEP files

“…The applications of feature recognition or 3D shape comparison span multiple disciplines such as computer vision (Büker et al, 2001), artifact comparison (Koutsoudis et al, 2012) and molecular biology (Firdaus-Raih et al, 2014). In the field of manufacturing, feature recognition has immense potential applications such as, extraction of manufacturing features such as holes (for machining tool path generation), extraction of tolerance specifications (for machine selection required for manufacturing) and extraction of similar part from a database for manufacturing process design.…”

Realistic Simulation of Cultural Heritage

“…In addition, Koutsoudis & Pavlidis (2011), proposed a novel approach for navigating within complex cultural scenes by exploiting content-based retrieval descriptors. Koutsoudis et al (2012), proposed a content-based navigation framework for a virtual museum, based on metadata that describe the exhibits and thus providing a semantic similarity-based navigation. In (Doulamis, Liarokapis, Petridis, & Mialous, 2012) a serious game is proposed based on scenarios derived from the cultural heritage domain and attempts to enrich the player's knowledge by spreading a mystery in ancient times.…”
