Hi there, I am Sébastien Grand!

I'm a 1st year PhD student at IMT Mines Albi working on robust and adaptive Deep Multimodal Fusion.

Previously, I received a M.S in Computer Science and Mathematics, a double diploma from INP ENSEEIHT and INSA Toulouse in 2023.

Then, I worked for a year at EPSI Radar at developing Computer Vision classification models for radar data.

Experience

2023-2024

Research Engineer EPSI Radar

Manager: Bruno Mériaux, Ph.D

Classification of human activities vs. environment, based on micro-Doppler radar signals, leveraging Convolutional Neural Networks (CNNs) for robust spectrum-based classification. • Developed an ML for human activity detection based on micro-Doppler spectrum classification using Convolutional Neural Networks (CNNs). • Improvement in detection performance compared with the previous model. • Development of the inference pipeline in C++ using ONNXruntime for further deployment.

Aug. 2022 - Feb. 2023

Research Intern (Master Thesis) Hensoldt Analytics

Advisor: Jonathan Kobold, Ph.D

• Generated robust motion maps based on videos captured by UAV cameras to feed an object detector and improve its performance at detecting drones. • Developed motion compensation algorithm using Panoramic View building (Image stitching), motion extraction algorithm using Robust PCA, and addition of the motion map to the RGB frame to improve drone detection. • Modified YOLOX (object detector) architecture to add the motion map as a new feature. • Enhanced motion extraction algorithm and improved object detector performance with the addition of the motion map as a new feature.
