Radio-frequency ablation is a difficult operative task that requires a precise needle positioning in the centre of the pathology. This article presents an augmented reality system for hepatic therapy guidance that superimposes in real-time 3D ...

This paper presents an innovative 3D reconstruction of ancient fresco paintings through the real-time revival of their fauna and flora, featuring groups of virtual animated characters with artificial-life dramaturgical behaviours in an immersive, fully ...

In this paper we describe an approach to computer-aided sculpting concerned with the creation and modification of digital models based on physical abstract sculptures. We begin by presenting a survey of current methods for the creation of computer-aided ...

Work on remote collaboration has often focused on the person space created by a conventional videoconference where the participants see each other's faces, but we argue that a task space containing shared visual information is more important for most ...

Domain decomposition is a popular technique for solving large computational problems that require data to be divided into smaller sub-domains. The exact manner of decomposition depends on the computational needs of the algorithm and often introduces ...

This paper presents a multi-resolutional surface deformable model with physical property adjustment scheme and shape-preserving springs to represent surface-deformable objects efficiently and robustly. In order to reduce the computational complexity ...
