The propose a three-level algorithm to detect animal hunt events in wildlife documentaries. The first level extracts texture, color and motion features, and detects motion blobs. The mid-level employs a neural network to verify the relevance of the detected motion blobs using the extracted color and texture features. This level also generates shot summaries in terms of intermediate-level descriptors which combine low-level features from the first level and contain results of mid-level, domain specific inferences made on the basis of shot features. The shot summaries are then used by a domain-specific inference process at the third level to detect the video segments that contain hunts.

After a decade from its origin, MPEG, with its current MPEG-4 project, is now facing the challenge of providing a future-proof multimedia toolkit which aims at incorporating new and emerging technologies while ensuring backward compatibility with its previous and successful audio-visual standards. The paper provides an overview of the standard, focusing mainly on the video decoding aspects that, by their nature, represent one of the most peculiar features of the future specifications which are scheduled to become an international standard by the beginning of year 1999. The paper first briefly introduces the MPEG standards, focusing on the MPEG-4 Video part of the specification, giving an extensive presentation of a coding/decoding video process. The main part of the paper is focused on the optimization performed to realize a real time software video decoder based on the MMX/sup TM/ architecture compliant to the VM 8 MPEG-4 Video standard. A comparison with the reference video decoder is also presented.

General purpose haptic interfaces are receiving increasing attention in the field of robotics and mechatronics, because of their great flexibility for simulating many different kinds of interaction between user and virtual objects/environments. The paper describes a special-purpose haptic interface devoted to simulate the behavior of knobs and push buttons, with the aim of performing tests on different geometries and designs. In particular, the paper focuses on the control of the presented device, whose task is to provide a reaction to the external solicitation as similar as possible to that of a real knob or button.

We describe the design and evaluation of CamWorks, a system that employs a video camera as a means of supporting capture from paper sources during reading and writing. The user can view a live video image of the source document alongside the electronic document in preparation. We describe a novel user interface developed to support selection of text in the video window, and several new techniques for segmentation, restoration and resolution enhancement of camera images. An evaluation shows substantially faster text capture than with flatbed scanning.

This paper describes a design that implements a Virtual Museum for its access through Internet. It can not only provide the information so far available in the Web, but also allows a three-dimensional (3D) walk through the whole Museum, watching its collections, plus a presentation of single objects in 3D, with different resolutions according to each visitor interests and with a real possibility of visitor-object interaction. All this opens a wide new path of investigation, as it brings 3D into Internet and means a contribution to the increase of interactivity in Web pages.

Conferencing applications require an efficient conference control service. This paper introduces the main features of a conference control service based on the CORBA event service using the Java platform, under development at the Communications and Telematic Services Group of the University of Coimbra. This framework is based on the ITU T.120 recommendations, with reliable multicasting communication for both data and control information. The control service extends the CORBA Event Service architecture with mechanisms for reliable IP multicast communication, with total ordering of the events transmission, filtering and fragmenting/reassembling of large messages.

JWeb is a development environment for complex WWW applications, based upon the HDM model. JWeb (entirely written in Java) consists of two different parts: the development environment and the execution environment. The development environment allows the definition of the conceptual structure of the application, the creation of a supporting DataBase and the DataBase population. The execution environment allows the running of the application, possibly after some customization operations. We envision three main ways of using JWeb: as a training tool, for students and practitioners; as a fast prototyping tool, to test different design hypothesis, and to come up with a final design; as a tool for fast development and deployment of complex, high quality, Web applications.

HIPS is a project recently funded by the European Commission within the I-Cube initiative whose main aim is to study new technologies and interaction modalities that allow people to navigate both a physical space and a related information space at the same time, with a minimal gap between the two. The project envisages a portable electronic tour guide (to exhibitions, museums, archaeological sites, expositions distributed over a city, and to cities themselves) which empowers visitors to determine themselves the structure of a tour, according to their own criteria, interests and needs and which allow different information delivery modalities.

Lecture exchanges are increasing year by year. To promote this distance education systems have been developed and put into practical use. As a step further, a virtual space distance education platform called HyperClass has been proposed. HyperClass is a class where a teacher and students who are at different locations, in reality their avatars, are brought together through the communication network, and they can have classes and do cooperative work as if they were attending the same classroom. Any multimedia materials for education can be introduced into HyperClass. HyperClass is based on HyperReality (HR). HR is the concept of combination of virtual reality and real reality. A prototype system for HyperClass has been developed and the 3D (three dimensional) objects of Japanese heritage were introduced into HyperClass. To evaluate the efficiency and effectiveness of HyperClass, an experiment has been carried out by interconnecting between Waseda University and Victoria University of Wellington through the Internet. Good results have been obtained.
