t-LiDAR point cloud filtering for forest tree reconstruction
We analyze and filter or correct the noise in t-LiDAR point clouds due to multiple hits of a laser beam with the scene. We use the cleaned point cloud to enhance forest tree reconstruction methods.

Plant clustering into elementary units
We propose a spectral clustering approach to segment a 3D point cloud of a plant (typically acquired with a laser scanner device) into elementary units (branches, petioles, leaves).

Ontology-based anatomical segmentation
To automatically segment a 3D mesh of a human organ into anatomical meaningful parts, we propose to benefit from standardized anatomy information, organized in an ontology (for instance myCorporisFabrica).

Automatic cerebral aneurysm localization and quantification
We propose a simple method to detect, locate and quantify the size and shape of aneurysms on blood vessels, to help neurosurgeons before operation.
