Illustrator's Depth: Monocular Layer Index Prediction for Image Decomposition

CVPR 2026

We introduce Illustrator's Depth, a novel definition of depth that addresses a key challenge in digital content creation: decomposing flat images into editable, ordered layers. Inspired by an artist's compositional process, illustrator's depth infers a layer index for each pixel, forming an interpre

Bayesian Experimental Design Via Contrastive Diffusions

ICLR 2025spotlight

Bayesian Optimal Experimental Design (BOED) is a powerful tool to reduce the cost of running a sequence of experiments. When based on the Expected Information Gain (EIG), design optimization corresponds to the maximization of some intractable expected *contrast* between prior and posterior distribu…

ShapeShifter: 3D Variations Using Multiscale and Sparse Point-Voxel Diffusion

CVPR 2025poster

This paper proposes ShapeShifter, a new 3D generative model that learns to synthesize shape variations based on a single reference model. While generative methods for 3D objects have recently attracted much attention, current techniques often lack geometric details and/or require long training times…

PASOA- PArticle baSed Bayesian Optimal Adaptive design

ICML 2024poster

We propose a new procedure named PASOA, for Bayesian experimental design, that performs sequential design optimization by simultaneously providing accurate estimates of successive posterior distributions for parameter inference. The sequential design process is carried out via a contrastive estimati…

BPNet: Bézier Primitive Segmentation on 3D Point Clouds

IJCAI 2023poster

This paper proposes BPNet, a novel end-to-end deep learning framework to learn Bézier primitive segmentation on 3D point clouds. The existing works treat different primitive types separately, thus limiting them to finite shape categories. To address this issue, we seek a generalized primitive segmen…

VoroMesh: Learning Watertight Surface Meshes with Voronoi Diagrams

ICCV 2023poster

In stark contrast to the case of images, finding a concise, learnable discrete representation of 3D surfaces remains a challenge. In particular, while polygon meshes are arguably the most common surface representation used in geometry processing, their irregular and combinatorial structure often mak…

Real-Time Multi-SLAM System for Agent Localization and 3D Mapping in Dynamic Scenarios

IROS 2020poster

This paper introduces a Wearable SLAM system that performs indoor and outdoor SLAM in real time. The related project is part of the MALIN challenge which aims at creating a system to track emergency response agents in complex scenarios (such as dark environments, smoked rooms, repetitive patterns, b…

Anti-cropping blind resynchronization for 3D watermarking

ICASSP 2015accepted

Radial-based 3D watermarking alters the distances between the center of mass of the 3D mesh and its vertices. These watermarking systems are inherently sensitive to cropping. To address this limitation, this paper introduces a complementary blind resynchronization module to transmit critical synchro…
