At the level of life:

1996: Born

1996-current: Figuring things out

But more has happened all along on the outside. At the level of human life. I feel modeling is the only version of truth we know which does not reflect the absolute truth and this is the aspect of all sciences and life in general that I enjoy. And so I've been exploring physics-based and data-based explicit and implicit models:

Currently: I am a Research Engineer in the MORPHEO team at Inria Centre at the University Grenoble Alpes under the supervision of Sergi Pujades.

Prior to: joining Inria, I did the Paris-Saclay AI track of the Computer Science Masters during which I did two internships at Naver Labs Europe in the Geometric Vision team, under the supervision of Boris Chidlovski and Leonid Antsfeld.

On predicting 3D bone locations inside the human body

Abdelmouttaleb Dakri*, Vaibhav Arora*, Léo Challier, Marilyn Keller, Michael J. Black, Sergi Pujades

We aim to predict bone locations using only external 3D body surface observations. Existing methods lack proper validation on clinical imaging data, often suffering from 3D-2D projection issues. We improve this by using a dataset of segmented skin and bones from 3D MRI images, refining a model (SKEL) to create SKEL-J, which accurately fits segmented bones and skin. Our results demonstrate that SKEL-J predicts bone locations more accurately than previous methods.

HIT: Estimating Internal Human Implicit Tissues from the Body Surface

Marilyn Keller, Vaibhav Arora, Abdelmouttaleb Dakri, Shivam Chandhok, Jürgen Machann, Andreas Fritsche, Michael J. Black, Sergi Pujades

This work leverages the fact that the shape of the body surface is correlated with the internal anatomy; e.g. from surface observations alone, one can predict body composition and skeletal structure. And so we learn to infer the 3D location of three important anatomic tissues given the SMPL body mesh: subcutaneous adipose tissue (fat), lean tissue (muscles and organs) and long bones. I worked on the dataset creation.

CroCo v2: Improved Cross-view Completion Pre-training for Stereo Matching and Optical Flow

Philippe Weinzaepfel, Thomas Lucas, Vincent Leroy, Yohann Cabon, Vaibhav Arora, Romain Brégier, Gabriela Csurka, Leonid Antsfeld, Boris Chidlovskii, Jérôme Revaud

Building on the recent cross-view completion framework, a variation of masked image modeling that leverages a second view from the same scene which makes it well suited for binocular downstream tasks. The applicability of this concept has so far been limited and this work explores different avenues of improvement. With these improvements, we show for the first time that state-of-the-art results on stereo matching and optical flow can be reached without using any classical task-specific techniques like correlation volume, iterative estimation, image warping or multi-scale reasoning, thus paving the way towards universal vision models. I worked on getting SOTA results on the Stereo Matching task.

CroCo: Self-Supervised Pre-training for 3D Vision Tasks by Cross-View Completion

Philippe Weinzaepfel, Vincent Leroy, Thomas Lucas, Romain Brégier, Yohann Cabon, Vaibhav Arora, Leonid Antsfeld, Boris Chidlovskii, Gabriela Csurka, Jérôme Revaud

The pretext task of cross-view completion where the first input image is partially masked, and this masked content has to be reconstructed from the visible content and the second image. This pretext task leads to significantly improved performance for monocular 3D vision downstream tasks. I worked on exploring the model to integrate the downstream task of Stereo Matching task.

Path Planning for Autonomous Platoon Formation

Ouafae El Ganaoui-Mourlan, Stephane Camp, Thomas Hannagan, Vaibhav Arora, Martin De Neuville, Vaios Andreas Kousournas

This work proposes an approach that enables a vehicle to autonomously join a platoon with optimized trajectory in the presence of dynamical traffic obstacles. A notable aspect is the use of Model Predictive Control (MPC) optimization of the planned path, in conjunction with a variant of the Rapidly-exploring Random Trees (RRT*) algorithm for the purpose of platoon formation.

On-Road and Chassis Dynamometer Evaluation of a Pre-Transmission Parallel PHEV

Miriam Di Russo, Vaibhav Arora, Ronghui Lyu, Jerry C. Ku

This paper details the vehicle testing activities performed during the Year 4 of the EcoCAR 3 competition by the Wayne State University team on a Pre-Transmission Parallel PHEV. The paper focuses on two main testing platforms: the chassis dynamometer and the closed-course track (on-road).
