Figure 1. Statistics of our novel light and image collection database. For each model in our novel light and image collections database, we show (row-wise) its name, the number of images used in the SfM+PMVS reconstruction, the number of images with corresponding HDR light probes, and a rendering of the mesh obtained with Poisson reconstruction. The mesh textures are obtained by projecting the ...

2-D mesh-based motion compensation preserves neighboring relations (through connectivity of the mesh) as well as allowing warping transformations between pairs of frames; thus, it eeectively eliminates blocking artifacts that are common in motion compensation by block matching. However , available 2-D mesh models, whether uniform or nonuniform, enforce connectivity everywhere within a frame, wh...

The quality of numerical simulations of processes that are modeled by partial differential equations strongly depends on the quality of the mesh that is used for their discretization. This quality is affected, for example, by mesh smoothness, or discretization error. To improve the mesh, a functional that is in general nonlinear must be minimized (for example, the L approximation error on the m...

The theory of optimal size meshes gives a method for analyzing the output size (number of simplices) of a Delaunay refinement mesh in terms of the integral of a sizing function over the input domain. The input points define a maximal such sizing function called the feature size. This paper presents a way to bound the feature size integral in terms of an easy to compute property of a suitable or...

Several factors must be considered in deciding which mesh to use for a ventral hernia repair. Open hernia repairs with no exposure of mesh to viscera can be performed with unprotected synthetic mesh, preferably a "lightweight" option. For open repair with high risk for fascial dehiscence and visceral exposure to mesh, and for open underlay repair and laparoscopic underlay repair, recommendation...

The aim of this subtask has been to develop a manager for structured multiblock grids. The focus of the development has been on the block topology, of which the manager should have full control. The manager should also be easy to expand, in particular with new ways to describe the geometry of blocks in the grid. Typically grid generation involves a good deal of trial and error. Consequently the...

Processing noisy point data is a tedious task. It often requires smoothing and meshing, followed by mesh processing algorithms. In this work we present a robust filter which operates directly on points using higher order surface approximations, computed iteratively. We extend the bilateral filter by using and filtering surface curvature, and introducing a quality parameter based on our local su...

This paper describes a novel method for constructing triangle meshes from noisy and non-uniformly distributed 3D points. It consists of two steps. (1) Noise point removal uses clustering algorithm and epipolar constraint method to identify and remove noise points from the 3D points. (2) Constructive polygonization algorithm interpolates cleaned 3D points to construct a triangle mesh of the obje...

This paper describes a hierarchical registration process using the iterative closest point algorithm combined with a Progressive Mesh. To find the exact pose of objects in a robotic bin picking process we simulate the appearance of object poses and compare them with the real range data provided by laser range sensors. The coarse pose is estimated in a first step and then refined with the well k...
