Résumé: La modélisation géométrique et la sémantisation de scènes intérieures à partir d’échantillon de points et un sujet de recherche qui prend de plus en plus d’importance. Le traitement d’un ensemble volumineux de données est rendu difficile d’une part par le nombre élevé d’objets parasitant la scène et d’autre part…
June 23, 2pm in room Byron beige The emergence of 3D printing technology steers the investigation of new geometric problems. In this talk I will introduce three novel results in the realm of 3D printing and design of geometric models. The production cost of 3D printing is directly related to…
June 22, room Byron beige at 10:30 am Converting an unstructured mesh into a more structured model is a fundamental building block in many applications, such as reverse engineering and animation. In spite of many attempts to automate this task there still exists no satisfactory method for practical applications: some…
(Friday June 12th, 10:30am in room Byron beige) Abstract: Implicit functions are among the most convenient tools for surface description as they do not require any parameterization on the given point cloud. In this talk, I will present a fast and flexible reconstruction technique based on implicit b-splines. As the…
May 21, 3pm in room Byron blanc (downstairs) ABSTRACT: Today fabricating an appropriate 3D model using a low-cost 3D printer is as easy as printing a textual document, but creating a 3D model which is actually “appropriate” for printing is definitely complicated. A 3D model can be produced either from…
May 22, 2015 (2pm) – Euler Violet Title: Robust Shape Reconstruction from Defect-Laden Data Abstract: Surface reconstruction from point clouds is a widely explored problem in geometry processing. Although a high number of reliable methods have been developped over the last two decades, they often require additional measurements such as…
May 13 2015, Byron blanc. In this presentation we first introduce an iterative projection technique for parameterizing and fitting exactly a point cloud as a sample of a 4-edges (data) surface. This method is mainly based on the estimation of the so called “closest point parameters”, which requires an initial…
Abstract: Image segmention is the task of partitioning an image into a non-overlapping set of regions. It is well known that the inclusion of high level cues (e.g., object shape) can significantly enhance the performance of the techniques. However, their inclusion in typical segmentation schemes is not trivial and currently…
November 12, 2014 – Euler Violet Title: Robust 3D Watermarking Abstract: 3D models are valuable assets widely used in the entertainment industry and likely to face piracy issues. This presentation summarizes my Ph.D. research on the protection of static meshes through robust watermarking. Watermarking enables copyright holders to perform traitor-tracing…
Seminar by Michael Wand on October 1 (Wednesday) at 10am in room Byron Beige Title: Building Blocks for Shape Analysis and Synthesis Abstract: In this talk, I would like to talk about some recent work in which we decompose geometry into elementary building blocks and subsequently reassemble these to create shape variations. The first…
