A cellular model for multi-objects . . .
, 2001
"... We deal in this paper with complex three-dimensional scenes, partitioned into several objects of any shape, and with varying local dimensions. We propose a consistent topological modeling of such scenes, based on a cellular model. We introduce a definition of simple elements for any adjacency graph- ..."

-based geometrical structure. Then we prove a local characterization of simple cells of a cellular model, in the case of two objects, and of any number of objects. This characterization allows to define homotopic deformations of a complex scene.
Volumeshop: An interactive system for direct volume illustration
- PROCEEDINGS OF IEEE VISUALIZATION 2005
, 2005
"... Illustrations play a major role in the education process. Whether used to teach a surgical or radiologic procedure, to illustrate normal or aberrant anatomy, or to explain the functioning of a technical device, illustration significantly impacts learning. Although many specimens are readily availabl ..."

appeal of traditional illustrations, but can be interactively altered and explored. In this paper we present methods to realize such a system which combines artistic visual styles and expressive visualization techniques. We introduce a novel concept for direct multi-object volume visualization which
Multi-featured Multi-scale Deformable Model for Three-dimensional Surface Extractio from Volumetric Image
"... Deformable surface models provide a very attractive method for segmenting the three-dimensional shape of complex and various internal organs from volumetric medical images. However, although researchers have succeeded in overcoming some of the limitations of this approach, there still exist several ..."

significant unsolved problems. In this paper, we propose a multi-featured multi-scale deformable surface model as a solution to three of these problems: model initialization dependency, inability to extract object concavities, and model selfintersection. The multi-scale approach, in which w progressively
Optimization-Based Development of Compact Image Sensor with Rounded Silicon Device through Customized Criteria Formation and Multi-Objective Optimization
"... As camera module has been installed to cellular phones, its thickness dominates their miniaturization and its performance becomes critical to their marketability. It was found that if sensor device made of single crystal silicon could be bended and bonded to spherical substrate of the small curvatur ..."

method, in which target and limit values are set for each objective and that is effective for optimization practices, is used for formulating this multi-objective optimization problem as a single objective one. A genetic algorithm is used for solving the problem because of its underlying multiple-peakiness.
Hybrid cellular-functional . . .
"... An approach to modeling heterogeneous objects as multidimensional point sets with multiple attributes (hypervolumes) is presented. Attributes given at each point represent object properties of arbitrary nature (material, physical, etc.). A proposed theoretical framework is based on a hybrid model of ..."

A Cellular Model for the Evolutionary Development of Lightweight Material with an Inner Structure
"... We present a model of simulated evolutionary development on the basis of cells as building blocks for growth. In this model, cells grow and interact in a three-dimensional (3D) environment, where development is controlled by a simple genome. Using cell-cell interaction such as differential adhesion, ..."

Dense Image Registration through MRFs and Efficient Linear Programming
, 2008
"... In this paper we introduce a novel and efficient approach to dense image registration, which does not require a derivative of the employed cost function. In such a context the registration problem is formulated using a discrete Markov Random Field objective function. First, towards dimensionality re ..."

"... Abstract. This paper presents a Bayesian multi-scale three dimensional deformable template approach based on a medial representation for the segmentation and shape characterization of anatomical objects in medical imagery. Prior information about the geometry and shape of the anatomical objects und ..."

A joint physicsbased statistical deformable model for multimodal brain image analysis
- IEEE Trans. Med. Imaging

"... Abstract—A probabilistic deformable model for the represen-tation of multiple brain structures is described. The statistically learned deformable model represents the relative location of different anatomical surfaces in brain magnetic resonance images (MRIs) and accommodates their significant varia ..."
