Extended Geometry based Watermarking of 3D Meshes: Improving robustness of geometrical 3D mesh watermarking by introducing mesh regularization

Digital watermarking has been used extensively in media in recent years. Yet, there are still relatively few techniques for watermarking 3D meshes. In this paper we implement a watermarking algorithm proposed by O. Benedens that encodes a bit string in the distribution of the normals of the faces of the mesh and investigate a method to improve...

On the accuracy and convergence of the finite element method for truss and frame structures

During applied mechanics courses for undergraduates, the words `finite element' will be mentioned if a structural problem is so complex that it cannot be solved analytically or simply because it would require too much time to solve it by hand. The lecturer refers to a software package and explains how to work with it. Unfortunately, during these...

3D-guided Biopsy

Systems providing assistance during a biopsy or an autopsy can be found in various medical centers and hospitals, today. Traditionally, CT(computed tomography) and MRI(magnetic resonance imaging) scans are used to produce detailed 3D models and offer support during this procedures. Unfortunately, the high doses of radiation which are involved...

3D Scenario Editor

Het doel van ons bachelorproject was om de mogelijkheden te onderzoeken voor een intuïtieve 3D editor. Deze editor moest de beperkingen van een 2D editor verhelpen. De door ons gevonden oplossing diende te worden ondersteund met een implementatie in EVE, het visualisatieplatform van TNO. Nadat het Plan van Aanpak2 geschreven was zijn we meteen...

Procedural Filters

Tributing to the GATE project by TNO, this application was designed to create an extra layer between the project and 3D modelling artists. New users are now able to place procedural content in their 3D worlds, without knowing much of the environment or programming. A general filter can be created to apply to the environment, without knowing...

Final Report Flock of Birds System

Report describing the development process on the Flock of Birds Visualizer software, used to acquire and visualize measurements of shoulder movements for medical research. The major final results of the process consist of a system able to communicate with the sensor based tracking hardware, the Flock of Birds. Secondly, development has resulted...
