چکیده

Smoothing space curves has several applications in reverse engineering, CAD modeling and animation. We propose a 3D curve smoothing algorithm with the primary focus on smoothing boundaries of point clouds obtained during reverse engineering laser scanned models. While several point cloud denoising methods exist that handle the normal noise in the data, the boundary curve may still contain tangential noise. Our space curve smoothing algorithm can be used to obtain models with smooth boundaries. keywords: denoising, boundary smoothing, MLS projection, point clouds

Robust Moving Least-squares Fitting with Sharp Features

1. Briefly summarize the paper’s contributions. Does it address a new problem? Does it present a new approach? Does it show new types of results?  [AS] This paper presents a new robust moving least squares (MLS) approach to define a surface from a potentially noisy point set. Using techniques from robust statistics to determine neighborhoods used by MLS, this approach produces a piecewise smoo...

Sharp feature preserving MLS surface reconstruction based on local feature line approximations

Sharp features in manufactured and designed objects require particular attention when reconstructing surfaces from unorganized scan point sets using moving least squares (MLS) fitting. It’s an inherent property of MLS fitting that sharp features are smoothed out. Instead of searching for appropriate new fitting functions our approach computes a modified local point neighborhood so that a standa...

Projective Reconstruction of 3D-curves from its 2D-images using Error Models and Bundle Adjustments

In this paper, an algorithm for projective reconstruction of general 3D-curves from a number of its 2D-images taken by uncalibrated cameras is proposed. No point correspondences between the images are assumed. The curve and the view points are uniquely reconstructed, modulo projective transformations. The algorithm is divided into two separate algorithms, where the output of the rst is used as ...

Geometric Flows of Curves in Shape Space for Processing Motion of Deformable Objects

We introduce techniques for the processing of motion and animations of non-rigid shapes. The idea is to regard animations of deformable objects as curves in shape space. Then, we use the geometric structure on shape space to transfer concepts from curve processing in Rn to the processing of motion of non-rigid shapes. Following this principle, we introduce a discrete geometric flow for curves i...
