A Backpack Full of Skills: Egocentric Video Understanding with Diverse Task Perspectives

no code implementations5 Mar 2024 Simone Alberto Peirone, Francesca Pistilli, Antonio Alliegro, Giuseppe Averta

Human comprehension of a video stream is naturally broad: in a few instants, we are able to understand what is happening, the relevance and relationship of objects, and forecast what will follow in the near future, everything all at once.

PolyDiff: Generating 3D Polygonal Meshes with Diffusion Models

no code implementations18 Dec 2023 Antonio Alliegro, Yawar Siddiqui, Tatiana Tommasi, Matthias Nießner

In contrast to methods that use alternate 3D shape representations (e. g. implicit representations), our approach is a discrete denoising diffusion probabilistic model that operates natively on the polygonal mesh data structure.

MeshGPT: Generating Triangle Meshes with Decoder-Only Transformers

2 code implementations27 Nov 2023 Yawar Siddiqui, Antonio Alliegro, Alexey Artemov, Tatiana Tommasi, Daniele Sirigatti, Vladislav Rosov, Angela Dai, Matthias Nießner

We introduce MeshGPT, a new approach for generating triangle meshes that reflects the compactness typical of artist-created meshes, in contrast to dense triangle meshes extracted by iso-surfacing methods from neural fields.

OpenPatch: a 3D patchwork for Out-Of-Distribution detection

no code implementations5 Oct 2023 Paolo Rabino, Antonio Alliegro, Francesco Cappio Borlino, Tatiana Tommasi

We advance the field by introducing OpenPatch that builds on a large pre-trained model and simply extracts from its intermediate features a set of patch representations that describe each known class.

3DOS: Towards 3D Open Set Learning -- Benchmarking and Understanding Semantic Novelty Detection on Point Clouds

1 code implementation23 Jul 2022 Antonio Alliegro, Francesco Cappio Borlino, Tatiana Tommasi

In recent years there has been significant progress in the field of 3D learning on classification, detection and segmentation problems.
