g-HDAF Multiresolution Deformable Models for Shape Modeling and Reconstruction
نویسندگان
چکیده
In this paper, we construct a new class of deformable models using new biorthogonal wavelets, named Generalized Hermite Distributed Approximating Functional (g-HDAF) Wavelets. The scaling functions of this new family are symmetric and the corresponding wavelets optimize their smoothness for a given number of vanishing moments. In addition, we embed these multiresolution deformable models to the physics-based deformable model framework and use them for fitting 3D range data. We have performed a number of experiments with both synthetic and real data with very encouraging results.

متن کاملIntroducing Multiresolution Representation in Deformable Object Modeling
The need to simulate the behaviour of biological tissues in virtual environments originated intense research to devise techniques for physically-based modeling of objects whose shape and topology can dynamically evolve. The relevant amount of computation required by the existing techniques and the growing complexity of the scenes to be simulated impose the study of more flexible methods that sh...
متن کاملsmall number of projections using deformable models
Abstract. X-ray tomographic image reconstruction consists of determining an object function from its projections. In many applications such as non-destructive testing, we look for a fault region (air) in a homogeneous, known background (metal). The image reconstruction problem then becomes the determination of the shape of the default region. Two approaches can be used: modeling the image as a ...
متن کاملShape Modeling and Shape Analysis Based on Singularities
To analyze given object shapes, it is necessary rst to model the shapes and then to analyze the models. This paper proposes a method of modeling and analyzing two-dimensional (2D) and three-dimensional (3D) shapes based on singularities. First, a function is dened on an object. The object is then modeled by the distribution of the singularities of the function. Finally, the extracted singular p...
متن کاملReconstruction, Registration, and Modeling of Deformable Object Shapes
Biological or biomedical objects, such as expressive human faces and growing brain tumors, and dynamic scenes, such as cars running on the roads, generally vary their shapes as linear combinations of a number of shape bases. With the expeditious development of computer and imaging technologies, the problems of reconstruction, registration, and modeling of such deformable shapes from image measu...
