Comparative Study of YOLO Architectures for Automated Wood Defect Detection Open
The North American residential construction industry relies on wood as the principal material for structural framing, as well as for kitchen cabinets, decorative trim moldings, and door casings. In this regard, wood quality is a key determ…

Real-Time Neural Materials using Block-Compressed Features Open
Neural materials typically consist of a collection of neural features along with a decoder network. The main challenge in integrating such models in real-time rendering pipelines lies in the large size required to store their features in G…

Feature Consistent Point Cloud Registration in Building Information Modeling Open
Point Cloud Registration contributes a lot to measuring, monitoring, and simulating in building information modeling (BIM). In BIM applications, the robustness and generalization of point cloud features are particularly important due to th…

Instant transport maps on 2D grids Open
In this paper, we introduce a novel and extremely fast algorithm to compute continuous transport maps between 2D probability densities discretized on uniform grids. The core of our method is a novel iterative solver computing the L 2 optim…

Evaluating the visibility threshold for a local geometric distortion on a 3D mesh and its applications Open
Les opérations géométriques appliquées aux maillages 3D introduisent des dis torsions géométriques qui peuvent être visibles pour un observateur humain. Dans cette thèse, nous étudions l’impact perceptuel de ces distorsions. Plus préciséme…

Visual Contrast Sensitivity and Discrimination for 3D Meshes and their Applications Open
In this paper, we first introduce an algorithm for estimating the visual contrast on a 3D mesh. We then perform a series of psychophysical experiments to study the effects of contrast sensitivity and contrast discrimination of the human vi…

Just Noticeable Distortion Profile for Flat-Shaded 3D Mesh Surfaces Open
It is common that a 3D mesh undergoes some lossy operations (e.g., compression, watermarking and transmission through noisy channels), which can introduce geometric distortions as a change in vertex position. In most cases the end users of…
