PØDA: Prompt-driven Zero-shot Domain Adaptation

1 code implementation6 Dec 2022 Mohammad Fahes, Tuan-Hung Vu, Andrei Bursuc, Patrick Pérez, Raoul de Charette

Domain adaptation has been vastly investigated in computer vision but still requires access to target images at train time, which might be intractable in some conditions, especially for long-tail samples.

SceneRF: Self-Supervised Monocular 3D Scene Reconstruction with Radiance Fields

no code implementations5 Dec 2022 Anh-Quan Cao, Raoul de Charette

As the latter are conditioned on a single frame, scene reconstruction is achieved from the fusion of multiple synthesized novel depth views.

MonoScene: Monocular 3D Semantic Scene Completion

1 code implementation CVPR 2022 Anh-Quan Cao, Raoul de Charette

MonoScene proposes a 3D Semantic Scene Completion (SSC) framework, where the dense geometry and semantics of a scene are inferred from a single monocular RGB image.

ManiFest: Manifold Deformation for Few-shot Image Translation

1 code implementation26 Nov 2021 Fabio Pizzati, Jean-François Lalonde, Raoul de Charette

To enforce feature consistency, our framework learns a style manifold between source and proxy anchor domains (assumed to be composed of large numbers of images).

Physics-informed Guided Disentanglement in Generative Networks

no code implementations29 Jul 2021 Fabio Pizzati, Pietro Cerri, Raoul de Charette

Image-to-image translation (i2i) networks suffer from entanglement effects in presence of physics-related phenomena in target domain (such as occlusions, fog, etc), lowering altogether the translation quality, controllability and variability.
