Conventional treatment of the subcondylar fractures of the mandible is challenging because of the medial and anterior displacement of the condylar fragment and the limited surgical field. Proximity of facial nerve, carotid ...

Medical illustrations have been used for a long time for teaching and communicating information for diagnosis or surgery planning. Illustrative visualization systems create methods and tools that adapt traditional illustration ...

Medical datasets are continuously increasing in size. Although larger models may be available for certain research purposes, in the common clinical practice the models are usually of up to 512x512x2000 voxels. These ...

Throughout the years, many shading techniques have been developed to improve the conveying of information in volume visualization. Some of these methods, usually referred to as realistic, are supposed to provide better ...

We present in this talk several applications of Information Theory concepts to Computer Graphics. Mutual information will be applied to Radiosity to obtain the better scene discretization. The concept of entropy will be ...

Although the visualization techniques are becoming faster and faster, the datasets also increase, and the time the radiologists are able to devote to a single analysis is limited. In this sense, we propose some techniques ...

Automatic computation of best views of objects are very useful. For example, they can be used as the starting point of a scene exploration, or to enrich galleries of objects available through Internet by adding an image a ...

The automatic selection of good viewing parameters is a very complex problem. In most cases, the notion of good strongly depends on the concrete application. Moreover, when an intuitive definition of good view is available, ...

In the last decade a new family of methods, namely Image-Based Rendering, has appeared. These techniques rely on the use of precomputed images to totally or partially substitute the geometric representation of the scene. ...

In this paper we explore a set of techniques to reduce the bandwidth in remote navigation systems. These systems, such as exploration of virtual 3D worlds or remote surgery, usually require higher bandwidth than the common ...
