Presentation

I am working on [4D-PTV (Particle Tracking Velocimetry)](https://www.4d-ptv.com/) also known as Lagrangian Particle Tracking (LPT) at French National Institute for Agriculture, Food, and Environment (INRAE). We are interested in tracking 3D particles in time using state-of-the-art techniques to understand new Lagrangian physics. The process contains four primary steps, 1- [3D particle position reconstruction](https://www.4d-ptv.com/PTV-method) 2- [Track initialization](https://www.4d-ptv.com/PTV-method/Track-Initialisation) to build the most reliable tracklets 3- [Particle motion prediction ](https://www.4d-ptv.com/PTV-method/Track-Prediction) 4- Optimization.
