About me

I'm a second year Computer Vision PhD student at IMAGINE (ENPC) and GeoViC (Ecole Polytechnique) labs. My research is focused on conditional generative models. I've worked with semantically conditioned GANs and focused on subject transfer in images. Currently living in France, i am French, Spanish and Colombian. I'm bilingual in both French and Spanish while having C1 level in English



SCAM! Transferring humans between images with Semantic Cross Attention Modulation

Published at: ECCV 2022

In this work, we introduce SCAM (Semantic Cross Attention Modulation), a system that encodes rich and diverse information in each semantic region of the image (including foreground and background), thus achieving precise generation with emphasis on fine details.

We use this new architecture to perform subject transfer and set a new state of the art for this task.

Open Source Contributions

  • TorchRL: Worked on the model based aspect of the library
  • torchmetrics: Improved the FID metric to work online, avoiding storing features.
  • huggingface/diffusers: Implemented the sampling for K-LMS sampler
