The paper deals with registration algorithms. Suitable procedures for the registration of image medical data are presented. During our work we used manual registration and point-based registration methods to register digitized slices of the temporal bone. To create referential points ...

In this paper we present a simple, consistent and yet powerful spectral extension to the Tagged Image File Format (commonly referred to as TIFF). This extension would presumably turn TIFF, which is already one of the most frequently used formats for "normal" ...

Nowadays, the available tools for lighting design are limited in scope and inappropriate for interactive or creative use. In this paper, we present a different approach to the lighting design problem - a new methodology that includes the geometry and materials of the scene, th...

In this paper we describe how to achieve nice-looking cartoon style rendering and animation utilising 3D input and animation control. Besides a technical description, we also show how this rendering is smoothly integrated into traditional 2D animations. This way we combine the benefits&...

This paper proposes a mathematical model to obtain a portion of the skin of a human head, warping the corresponding portion of neurocranium, using the skin thickness in the craneometrical points that defines the portion of neurocranium and the mesh of the skull contents...

In this study a new developed edge tracing method was applied to the pixel set formed from the numerical image of an object in order to obtain the characteristic vector which is very important in the recognition of an object. In this method, instead of detecti...

The issue of point location is an important problem in computer graphics and the study of e cient data structures and fast algorithms is an important research area for both computer graphics and computational geometry disciplines. When filling the interior region of&#...

As computer graphics educators we are able to collect and manipulate data in ways that only a few years ago would have been considered science fiction. With the dawn of every day there appears new programs and strategies for retrieving, storing, and editing our precious d...
