3D surface matching by local feature descriptors is a fundamental task in 3D object
registration, recognition, and retrieval. In view of 2D projected descriptors' information …

Machining contours on a large thin-walled part is a difficult task due to inevitable
deformation of the actual part. The deformation of the contour can significantly influence the …

Abstract 3D Local feature description is an essential work in 3D computer vision since a lot
of downstream techniques rely on point-to-point correspondences. Most of the existing …

The Laplace-Beltrami operator has established itself in the field of non-rigid shape analysis
due to its many useful properties such as being invariant under isometric transformation …

In this paper, a bijection, which projects the shape manifold as a linear manifold, is proposed
to simplify the nonlinear problems of shape analysis. Shapes are represented by the …

3D data can be instrumental to the computer vision field as it provides insightful information
about the full 3D models' geometry. Recently, with easy access to both computational power …

A fast local reference frame (LRF) construction method based on the signed surface
variation is proposed, which can adapt to the real-time applications such as self-driving, face …

3D process plant models (PPMs) in the process industry normally consists of thousands of
components. And, there are many similar local structures in the PPM. Due to the complex …

Cette thèse porte sur la reconnaissance et l'appariement de formes 3D pour des systèmes
intelligents de vision par ordinateur. Elle décrit deux contributions principales à ce domaine …
