Ivan Lopes

I am a fourth year PhD student at INRIA Paris, directed by Raoul de Charette. I am completing my PhD with research focused on computer graphics, material estimation, and controllable image generation. I received a MSc degree from Telecom SudParis. Previously, I spent a semester abroad at Linköping University, followed by an exchange program at Telecom Paris.

MatSwap: Light-aware Material Transfers in Images

Eurographics Symposium on Rendering (CGF), 2025

MatSwap enables photorealistic transfer of a given material onto a target surface in an image, handling complex interactions of appearance, geometry, and lighting without requiring manual input or UV mapping.

Material Transforms from Disentangled NeRF Representations

Eurographics Conference (CGF), 2025

A method to transfer material transformations across scenes. Building on disentangled NeRF representations, our approach learns to map Bidirectional Reflectance Distribution Functions (BRDF) from pairs of scenes observed in varying conditions.

Material Palette: Extraction of Materials from a Single Image

Conference on Computer Vision and Pattern Recognition (CVPR), 2024

Material Palette extracts a palette of PBR materials (albedo, normals, and roughness) from a single real-world image using diffusion priors.

DenseMTL: Cross-task Attention Mechanism for Dense Multi-task Learning

Conference on Applications of Computer Vision (WACV), 2023

This work proposes an architecture to perform multi-task learning by combining information from different tasks using correlation-guided and self-attention mechanisms.
