Mandible shape modeling using the second eigenfunction of the Laplace-Beltrami operator
نویسندگان
چکیده
The second Laplace-Beltrami eigenfunction provides an intrinsic geometric way of establishing natural coordinates for elongated 3D anatomical structures obtained from medical images. The approach is used to establish the centerline of the human mandible from CT and provides automated anatomical landmarks across subjects. These landmarks are then used to quantify the growth pattern of the mandible between ages 0 and 20.

Hot Spots Conjecture and Its Application to Modeling Tubular Structures
The second eigenfunction of the Laplace-Beltrami operator follows the pattern of the overall shape of an object. This geometric property is well known and used for various applications including mesh processing, feature extraction, manifold learning, data embedding and the minimum linear arrangement problem. Surprisingly, this geometric property has not been mathematically formulated yet. This ...
متن کاملPartial Shape Matching of 3D Models Based on the Laplace-Beltrami Operator Eigenfunction
The comparison and matching based on partial description of the 3D model is the current focus of study in the shape analysis. The partial description based on the eigenfunction of the Laplace-Beltrami operator is an important way. A large number of eigenfunction values of any point on the surface of the model form a eigenvector; based on this vector, K-means clustering method will be used to qu...

متن کاملShape-based Transfer Function Using Laplace-Beltrami Operator
We exploit the Laplace-Beltrami operator to represent shapes which in turn is used for designing a shape based transfer function for volume rendering. Laplace-Beltrami spectral measures are isometry invariant and are one of the most powerful ways to represent shape, also called “Shape-DNA”. Isosurfaces are extracted from the volume data and the Laplace-Beltrami operator is applied on these extr...

The ubiquity of the Laplace-Beltrami operator in shape analysis can be seen by observing the wide variety of applications where it has been found to be useful. Here we demonstrate a small subset of such uses with their latest developments including a scale invariant transform for general triangulated meshes, an effective and efficient method for denoising meshes using Beltrami flows via high di...
