Efficient facial animation integrating Euclidean and geodesic distance-based algorithms into radial basis function interpolation.
… covering a review of Euclidean and geodesic distance-based algorithms, and proposing a hybrid approach that tries to take the advantages of the two previous methods aided by pre-processed distance data to fasten the computations. Using motion capture performance based on the Facial …

Robust and Blind 3D Watermarking
… of spectral coefficients. Chapter 4 employs the geodesic distance to carry the bits based on the observation that the distribution of geodesic distance within a range is close to uniform. Two ways of embedding scheme are introduced. One is to modify the mean value and the distribution and the …

Skeleton-based visualization of massive voxel objects with network-like architecture
… a noise-insensitive measure based on the geodesic distance along the boundary to compute two-dimensional skeletons. The measure is able to retain thin object structures if they are geometrically important while ignoring noise on the object's boundary. This combination of properties is not …

Network theory applied to linguistics: new advances in language classification and typology
… features related to: average degree, average geodesic distance, clustering, entropy-based indices, assortativity, centrality, compactness etc. We also propose some new indices that can serve as additional characteristics of networks. The results obtained show that network models succeed in …

State and Dynamics Estimation in an Outdoor Multi-Drone Slung Load System
… achieves position errors of 0.1 m, and geodesic distance attitude errors around 0 ◦ . Real world testing shows errors of 0.2 m and 5 ◦ respectively. Applying extended Kalman filter and unscented Kalman filter formulations, simulated position estimates average around an error of 0 m, …

Fast and exact geodesic computation using Edge-based Windows Grouping.
Computing discrete geodesic distance over triangle meshes is one of the fundamental problems in computational geometry and computer graphics. As the “Big Data Era” arrives, a fast and accurate solution to the geodesic computation problem on large scale models with constantly increasing resolutions …

Automatic Alignment of 3D Multi-Sensor Point Clouds
… 3D surface descriptor, called the radial geodesic distance-slope histogram. Similar keypoints descriptors on the source and target datasets are then matched using bipartite graph matching, followed by a modified-RANSAC for outlier removal. The second proposed method is based on 2D keypoint …

Foundational Investigations & Astronomical Implications of Quantum Gravity
… recently been studied by Michor and Mumford. The geodesic distance between any two points on this space is zero. Here we show that this mathematical result translates to a description of a hot, zero entropy state and an arrow of time after the Big Bang. This is modeled as a far from equilibrium, …

The Measure and Meaning of Structural Similarity in the Brain
… similarity, each of which was aligned with geodesic distance from one of the two phylogenetically primitive areas (paleocortex and archicortex) predicted by the Dual Origin theory of cortical evolution. Genetic MIND gradients were more heritable than comparable gradients derived from GWAS of …

Estimation of Shared Functional Information Between Neural Areas
… of inter-areal subspaces, quantified using geodesic distances, reveals distinct communication patterns across brain states and cortical hierarchies. Our findings support the view that neural processing is fundamentally distributed, with shared population-level codes spanning multiple …
