FunPhase: A Periodic Functional Autoencoder for Motion Generation via Phase Manifolds

Marco Pegoraro, Evan Atherton, Bruno Roy +2

Learning natural body motion remains challenging due to the strong coupling between spatial geometry and temporal dynamics. Embedding motion in phase manifolds, latent spaces that…

A Scalable Attention-Based Approach for Image-to-3D Texture Mapping

Arianna Rampini, Kanika Madan, Bruno Roy +2

High-quality textures are critical for realistic 3D content creation, yet existing generative methods are slow, rely on UV maps, and often fail to remain faithful to a reference im…

Unsupervised Representation Learning for 3D Mesh Parameterization with Semantic and Visibility Objectives

AmirHossein Zamani, Bruno Roy, Arianna Rampini

Recent 3D generative models produce high-quality textures for 3D mesh objects. However, they commonly rely on the heavy assumption that input 3D meshes are accompanied by manual me…

Decoupling High and Low Frequencies for Faithful Image Generation with Fine Details

Tejaswini Medi, Hsien-Yi Wang, Arianna Rampini +1

Latent generative models compress images into learned embeddings prior to synthesis, and the generation quality critically depends on how faithfully these embeddings preserve visua…

Spectral Maps for Learning on Subgraphs

Marco Pegoraro, Riccardo Marin, Arianna Rampini +3

In graph learning, maps between graphs and their subgraphs frequently arise. For instance, when coarsening or rewiring operations are present along the pipeline, one needs to keep…

Instant recovery of shape from spectrum via latent space connections

Riccardo Marin, Arianna Rampini, Umberto Castellani +3

We introduce the first learning-based method for recovering shapes from Laplacian spectra. Given an auto-encoder, our model takes the form of a cycle-consistent module to map laten…

Correspondence-Free Region Localization for Partial Shape Similarity via Hamiltonian Spectrum Alignment

Arianna Rampini, Irene Tallini, Maks Ovsjanikov +2

We consider the problem of localizing relevant subsets of non-rigid geometric shapes given only a partial 3D query as the input. Such problems arise in several challenging tasks in…

Isospectralization, or how to hear shape, style, and correspondence

Luca Cosmo, Mikhail Panine, Arianna Rampini +3

The question whether one can recover the shape of a geometric object from its Laplacian spectrum ('hear the shape of the drum') is a classical problem in spectral geometry with a b…
