VQ‐Style: Disentangling Style and Content in Motion with Residual Quantized Representations

Computer Graphics Forum, EarlyView.
Abstract Human motion data is inherently rich and complex, containing both semantic content and subtle stylistic features that are challenging to model. We propose a novel method for effective disentanglement of the style and content in human motion data to facilitate style transfer.

Facial Similarity Measure for Recognizing Monozygotic Twins Utilizing 3D Facial Landmarks, Efficient Geodesic Distance Computation, and Machine Learning Algorithms

IEEE Access
Compared with 2D face recognition systems, 3D facial recognition has been a popular area of study in academia and industry because of its ability to detect human faces in an unconstrained environment more efficiently.

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

Non‐Rigid 3D Shape Correspondences: From Foundations to Open Challenges and Opportunities

Computer Graphics Forum, EarlyView.
Abstract Estimating correspondences between deformed shape instances is a long‐standing problem in computer graphics; numerous applications, from texture transfer to statistical modelling, rely on recovering an accurate correspondence map. Many methods have thus been proposed to tackle this challenging problem from varying perspectives, depending on ...

Affine connections for 2-osculating vector fields and geodesics

, 1989
Starting with the work of \textit{A. M. Pastore} [ Rend. Accad. Naz. Sci. Detta XL, IV. Ser. 22-23, 135-148 (1972; Zbl 0414.53008); Rend. Mat. Appl., VII. Ser. 1, 177-190 (1981; Zbl 0477.53018)]\ the authors study the relationship between the geodesics with respect to a connection for 2-osculating vector fields and the curves which are projections of ...

Totally geodesic property of the Hopf vector field

, 2005
We prove that the Hopf vector field is a unique one among geodesic covariantly normal unit vector fields on spheres such that the submanifold generated by the field is totally geodesic in the unit tangent bundle with Sasaki metric. As application, we give a new proof of stability (instability) of the Hopf vector field with respect to volume variation ...

Establishing Shape Correspondences: A Survey

Computer Graphics Forum, EarlyView.
Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

On the geometry of Riemannian manifolds with a Lie structure at infinity

International Journal of Mathematics and Mathematical Sciences, 2004
We study a generalization of the geodesic spray and give conditions for noncomapct manifolds with a Lie structure at infinity to have positive injectivity radius. We also prove that the geometric operators are generated by the given Lie algebra of vector

Vector fields, flows and geodesics on supermanifolds

Champs de vecteurs, flots et géodésiques sur les supervariétés Le résultat principal de cette thèse est de donner une définition de géodésique sur les supervariétés riemanniennes (\ca,g) paires (et aussi impaires) et de la justifier par un théorème reliant les courbes géodésiques avec le flot géodésique sur \text{T}^*\ca. Pour ce faire,
