Special Issue of CVIU on Model-based and Image-based 3D Scene Representation for Interactive Visualization Guest Editors Guido M. Cortelazzo, Department of Information Engineering, University of Padua, Italy Concettina Guerra, Department of Information Engineering, University of Padua, Italy Aim and scope A 3D scene generally cannot be adequately represented by a single picture or a collection of pictures, which can only reproduce one viewpoint or a collection of viewpoints, or even by a movie, which can reproduce only one visualization trajectory: the one which was followed by the operator during the taking. What characterizes human inspection is the viewer's freedom to choose at any instant his viewing distance and direction. 3D models and image-based methods offer the representation tools closest to direct inspection since they give the possibility of dynamically visualizing any view of a 3D scene or object under users' interaction. In this context the photorealistic reproduction of colour appearance is essential. The use of 3D scene representations for interactive visualization can be extended to a great deal of non traditional applications, ranging from e-commerce to cultural heritage, provided that a number of open issues concerning their realization and their remote visualization find adequate solutions. A central issue concerns the availability of procedures which make their realization from geometry and texture data gathered by inexpensive equipment as robust and automatic as possible. Since an important characteristic of 3D scene representations for interactive visualization is their remote usability, any contribution to their compression, transmission and remote visualization which may overcome or at least alleviate the difficulties of their distribution via the Internet or wireless channels would play a valuable service. This special issue will focus on topics relevant to the effective and inexpensive realization of 3D scene representations for interactive visualization and their remote use, such as: Multi-image processing Image-based rendering 3D photography 3D view registration and integration Multi-resolution 3D scene representation 3D texture acquisition and processing Compression and transmission of 3D scene representation Remote visualization of 3D scene representation 3D video and 3D telepresence Only original, high-quality papers, in-line with the CVIU guidelines, will be considered for publication in this special issue. Every contribution to the special issue is bound to undergo standard CVIU reviewing policy.
