3D CT Segmentation for Clinical Evaluation of Knee Prosthesis Operations
(The Eurographics Association, 2006)
In surgical knee replacement, the damaged knee joint is replaced with artificial prostheses. An accurate clinical evaluation must be carried out before applying knee prostheses to ensure optimal outcome from surgical ...
A New Descreening Technique in the Frequency Domain
(The Eurographics Association, 2006)
In this paper a new algorithm to obtain a continuous tone image starting from a halftoned one is proposed. This descreening technique is based on Butterworth filtering in the frequency domain. It removes the pattern of the ...
Compressed SVG Representation of Raster Images Vectorized by DDT Triangulation
(The Eurographics Association, 2006)
This paper presents a portable compression algorithm applied to raster data images properly triangulated by using DDT (Data Dependent Triangulation). In particular the input source data are encoded to be rendered by standard ...
SVG Vectorization by Statistical Region Merging
(The Eurographics Association, 2006)
In this paper a novel algorithm for raster to vector conversion is presented. The technique is mainly devoted to vectorize digital picture maintaining an high degree of photorealistic appearance specifically addressed to ...
Color Palette Images Re-indexing by Self Organizing Motor Maps
(The Eurographics Association, 2006)
Palette re-ordering is a well known and very effective approach for improving the compression of color-indexed images. If the spatial distribution of the indexes in the image is smooth, greater compression ratios may be ...
A Survey of Digital Mosaic Techniques
(The Eurographics Association, 2006)
Art often provides valuable hints for technological innovations especially in the field of Image Processing and Computer Graphics. In this paper we survey in an unified framework several methods to transform a raster input ...
