Multi-view stereo reconstruction techniques yield inherently multi-scale point data typically fed into surface reconstruction algorithms. Following the intuition of scale space we assume that sample points originate from smoothed versions of the original surface. The smoothing can be characterized by a smoothing kernel that suppresses fine-scale structures. In this paper, we propose a surface r...

While performing mechanical reverse engineering, 3D reconstruction processes often encounter difficulties capturing small, highly localized surface information. This can be the case if a physical part is scanned for life-cycle management or robust design purposes, with interest in corroded areas scratched coatings. The limitation partly due to insufficient automated frameworks handling – inform...

GOPI MEENAKSHISUNDARAM: Theory and Practice of Sampling and Reconstruction of Manifolds with Boundaries (Under the direction of Prof. Jack Snoeyink) Surface sampling and reconstruction are used in modeling objects in graphics and digital archiving of mechanical parts in Computer Aided Design and Manufacturing (CAD/CAM). Sampling involves collecting 3D points from the surface. Using these point ...

In practice of surface reconstruction it often happens that a used algorithm is not capable to reconstruct a CAD-model completely. In this work a method to repair defects of a CAD-model is offered. For surface reconstruction inside damaged regions this method uses force lines of a specially constructed tensor field. This method can be considered as a post-processing step for any surface reconst...

We present coherent speckled x-ray diffraction patterns obtained from a monolayer of surface atoms. We measured both the specular anti-Bragg reflection and the off-specular hexagonal reconstruction peak for the Au(001) surface reconstruction. We observed fluctuations of the speckle patterns even when the integrated intensity appears static. By autocorrelating the speckle patterns, we were able ...

The reconstruction of an object's shape or surface from a set of 3D points plays an important role in medical image analysis, e.g. in anatomy reconstruction from tomographic measurements or in the process of aligning intra-operative navigation and preoperative planning data. In such scenarios, one usually has to deal with sparse data, which significantly aggravates the problem of reconstruction...

Surface reconstruction means that retrieve the data by scanning an object using a device such as laser scanner and construct it using the computer to gain back the soft copy of data on that particular object. Surface reconstruction is a reverse method. It is very useful when in a particular object original data is missing without doing any backup. Hence, by doing so, the data can be recollected...
