Internships, Ph.D. and post-doc

I am always looking for good motivated students. If you want to do a post-doc with me or a Ph.D. (or an intership) under my supervision, have a look at these. Then feel free to contact me do discuss the different opportunities.

PCEDNet : A Lightweight Neural Network for Fast and Interactive Edge Detection in 3D Point Clouds. by Chems E. Himeur et al., ACM Transaction on Graphics 2022.

posted 01/09/2021

Watch these !

PCEDNet: We introduce a new 3D point cloud parametrization allowing very simple and fast to train/evaluate neural networks to classify edge points. This is so efficient that it outperforms current learning approaches in classification quality while processing up to 500 000 points per second on a standard mono-thread CPU implementation. It also enable interactive training to better fit user/application expectations (ACM Transactions on Graphics 2022).

by Chems Eddine Himeur et al. (see also STORM's YouTube Channel).

Plane reconstruction at different scales: We introduce a new graph data struture organizing 3D points by similar attribute (here normal orientation) at different scales. The use of set operators then allows us to efficiently extract strutures by similar attribute value stabe at several neighbor scales (Euroggraphics 2020).

by Thibault Lejemble et al. (see also STORM's YouTube Channel).

Implicit skinning free demo: Based on our TOG 2014 paper, we distribute a stand-alone demo software illustrating the skin deformations produced by the time dependent version of the implicit skinning. Downloads for Linux, MacOS and Windows are provided.

see also STORM's YouTube Channel.

Implicit kinning Maya plugin: We distribute a Maya plugin for commercial use, implementing both the time independent (2013) and the time dependent (2014) versions of the Implicit Skinning.
