I am mostly interested in Image-Based Rendering (IBR) and 3D reconstruction using deep learning approaches. In particular, I worked on developing scalable approaches for simultaneously learning to reconstruct and explore 3D environments. More recently, I have been working on Novel View Synthesis and surface reconstruction in radiance fields. Before that, I studied at the Ecole polytechnique as well as the &Eacutecole normale sup&eacuterieure Paris-Saclay where I obtained the MVA MS degree. </p> </div> <div class="container"> <h2>News</h2> <hr/> <p class="label date">04-2025</p> <a href="https://anttwo.github.io/matcha/">MAtCha</a> has been selected for a Highlight at CVPR 2025!<br> <p class="label date">04-2025</p> We just released the code for <a href="https://anttwo.github.io/matcha/">MAtCha</a>!<br> <p class="label date">03-2025</p> <a href="https://anttwo.github.io/matcha/">MAtCha</a> paper has been accepted to CVPR 2025!<br> <p class="label date">11-2024</p> I am very honored to be selected as one of the <a href="https://neurips.cc/Conferences/2024/ProgramCommittee#top-reviewers">Top Reviewers for NeurIPS 2024</a>!<br> <p class="label date">10-2024</p> I was in Milan for ECCV 2024, and had the pleasure to give an oral presentation of <a href="https://anttwo.github.io/frosting/">Frosting</a> and to meet many great people in the field.<br> <p class="label date">09-2024</p> I am very honored to be selected as one of the <a href="https://eccv.ecva.net/Conferences/2024/Reviewers#all-outstanding-reviewers">Outstanding Reviewers for ECCV 2024</a>!<br> <p class="label date">09-2024</p> We just released a <a href="https://github.com/Anttwo/sugar_frosting_blender_addon/">Blender Add-On</a> to import, edit and animate 3D scenes reconstructed with SuGaR and Frosting without a single line of code. <br> <p class="label date">08-2024</p> <a href="https://anttwo.github.io/frosting/">Gaussian Frosting</a> paper has been selected for an oral presentation at ECCV 2024!<br> <p class="label date">07-2024</p> <a href="https://anttwo.github.io/frosting/">Gaussian Frosting</a> paper has been accepted to ECCV 2024!<br> <p class="label date">04-2024</p> I was invited by <a href="https://scholar.google.com/citations?user=SXXEZhYAAAAJ&hl=en">Pr.
