The DHX project - globally shared cultural heritage
Palamidese P., Carreras C., Coltelli P.
The main features of the European DHX project are here reported. This project aims at providing ways of sharing and communicating heritage contents between museums wordlwide with VR representations, interaction paradigms, remotely controlled avatars. Several applications will be used to demonstrate different innovative technologies that range from computer vision and movement capture techniques to data base access for VR contents, to uniform storytelling and navigation approaches.Source: EVA 2004 Florence, Florence, Italy, 29 March - 2 April 2004

A dedicated interface to plan scenes with virtual characters
Palamidese P., Coltelli P.
This paper discusses how to design a multimedia application in which a number of characters perform a predefined set of actions. The basic concepts and techniques required by this kind of application include character animation, storytelling, and multimedia. This paper focuses on the prototyping issues and the designer need of making the starting plan of the whole story. The design process requires mainly the composition and integration of narrative structures and media and animated objects. We propose to integrate multimedia authoring styles and animation synthesis techniques to simplify and speed up designing, prototyping and editing. We state that available animation systems do not provide a suitable interface for developing large-scale applications and supporting non-expert authors. Sketching and planning stories containing human characters requires an animation tool dedicated to it. A story can be prototyped rapidly only if the interface supports the author expressly.

MIN A Metropolitan Interconnection Network
Coltelli P., Mannocci M., Rizzo L., Tarini F., Zini P.
A metropolitan network mostly built with teehnology and eomponents typieal of loeal networks is presented. The shared bus arehiteeture, the bit rate and the paeket format are taken from the IEEE 802.3 standard. High level protoeol implementations and network serviees available for Ethernet environments are used too. On the eontrary, a different channel-access protocol and possibly different eommunieation media are used. The main purpose is a transparent intereonneetion among loeal networks distributed all around a town, so that services typieally available in loeal environment ean be extended allover a town. A prototype of the network here presented is being implemented in Pisa.

Real-time measurement and analysis of translational and rotational speeds of moving objects in microscope fields
Coltelli P., Evangelisti M., Evangelista V., Gualtieri P.
This paper describes a digital system designed for the automatic detection and measurement of the velocity of moving objects in images acquired by means of a common TV-camera mounted onto a microscope. The main characteristics of this system are the following: 1) it can perform a realtime gray level difference between two successive frames in order to detect moving objects and to suppress stationary objects (subtraction procedure); usually the delay between two successive frames varies linearly from 40 msec to 1920 msec; 2) it reduces the size of images resulting from the subtraction procedure (difference images) and stores them in the frame memory; the result of these operation, all performed in real-time, is a film of time sequences; 3) it performs an automatic labelization in order to recognize the moving microorganisms and to calculate their area in each difference image; 4) it calculates and plots the variation of the average area of the cells moving in the microscope field; 5) it completes the analysis in few seconds.Source: Lecture notes in computer science 4826 (2007): 128–135.

VBP: Virtual Baptistery of Pisa
Palamidese P., Carreras F., Coltelli P.
VBP, the Virtual Baptistery of Pisa, is a virtual reality prototype for cultural heritage presentation and communication. It combines education and entertainment methods to create a playful even though correct way to deliver artistic and cultural information. The virtual reality provides added values to the public with respect to the traditional media, as it lets group multimedia contents from various sources in a unique virtual environment. The visitor can see situations that he cannot see in a real visit - a reference to another monument, a cross section, architectural details that are too high up- and also situations that attract his attention and curiosity -lighting and acoustic effects, meet remotely connected visitors, ask questions to synthetic guides-. VBP presents a scenographic representation of the Baptistery of Pisa for interactive and distributed exploration. VBP contains the concepts of non linear intersecting storylines based on storytelling methods and techniques that can fits various levels of users. In addition it is a general framework for developing new stories, and for changing and adapting the ones already created. VBP requires an immersive stereo visualization system equipped with adequate audio and interaction devices. When the proper VR hardware is not available, it can run on the PC screen as well, though one looses immersion characteristics. The beta version has been released in 2003 while the final version has been planned at half 2005.

Virtual reality storyboard: the case of the visual and acoustic tour of the Baptistery of Pisa
Palamidese P., Carreras F., Coltelli P., Massei L., Bigliazzi M.
This report contains the detailed storyboard design of a non-linear story that describes a virtual visit of the Baptistery of Pisa, developed within the European project DHX - Digital Artistic and Ecological Heritage Exchange - IST-2001-33476, and described into the "Deliverable D2e.4 - Storyboard of the research prototype scenario" of the project. The scenario architecture makes use of digital storytelling and traditional dramaturgic concepts such as scenes layout, timing, emotional effects, proper use of sound and user interaction. The user can control and modify the narration development, access to historical artistic information and finally meet avatars of remote users and share the visit with them. The application is conceived to run either in a local virtual reality system in a museum or in a multi-site multi-user networked virtual environment of museums that want to share cultural contentsSource: ISTI Technical reports, 2003

Low-resolution characterization of the 3D structure of the Euglena gracilis photoreceptor
Barsanti L., Coltelli P., Evangelista V., Passarelli V., Frassanito A. M., Vesentini N., Gualtieri P.
This paper deals with the first characterization of the structure of the photoreceptive organelle of the unicellular alga Euglena gracilis (Euglenophyta). This organelle has a three-dimensional organization consisting of up to 50 closely stacked membrane lamellae. Ionically induced unstacking of the photoreceptor lamellae revealed ordered arrays well suited to structural analysis by electron microscopy and image analysis, which ultimately yielded a low-resolution picture of the structure. Each lamella is formed by the photoreceptive membrane protein of the cell assembled within the membrane layer in a hexagonal lattice. The first order diffraction spots in the calculated Fourier transform reveals the presence of 6-fold symmetrized topography (better resolution about 90A). The 2D and 3D structural data are very similar with those recently published on proteorodopsin, a membrane protein used by marine bacterio-plankton as light-driven proton pump. In our opinion these similarity indicate that a photoreceptive protein belonging to the same superfamily of proteorodopsin could form the Euglena photoreceptor.Source: Biochemical and biophysical research communications (Print) 375 (2008): 471–476. doi:10.1016/j.bbrc.2008.08.045
