Variances of Cylinder Parameters Fitted to Range Data

Industrial pipelines are frequently scanned with 3D imaging systems (e.g., LADAR) and cylinders are fitted to the collected data. Then, the fitted as-built model is compared with the as-designed model. Meaningful comparison between the two models requires estimates of uncertainties of fitted model parameters. In this paper, the formulas for variances of cylinder parameters fitted with Nonlinear...

Variances of Plane Parameters Fitted to Range Data

Formulas for variances of plane parameters fitted with Nonlinear Least Squares to point clouds acquired by 3D imaging systems (e.g., LADAR) are derived. Two different error objective functions used in minimization are discussed: the orthogonal and the directional functions. Comparisons of corresponding formulas suggest the two functions can yield different results when applied to the same dataset.

Variances Are Not Always Nuisance Parameters

In classical problems, e.g., comparing two populations, fitting a regression surface, etc., variability is a nuisance parameter. The term “nuisance parameter” is meant here in both the technical and the practical sense. However, there are many instances where understanding the structure of variability is just as central as understanding the mean structure. The purpose of this article is to revi...

Estimating Cloth Draping Parameters from Range Data

In this paper we present a computer vision algorithm for estimating cloth parameters for mod-eling. In an analysis-by-synthesis manner, the algorithm compares the drape of the model with the range data and searches for the best t. It can be applied to any physics-based cloth model. The motivating application is fashion design using CAD systems, but the ability of the algorithm to estimate the s...

Statistical variances in traffic data

We perform statistical analysis of the single-vehicle data measured on the Dutch freeway A9 and discussed in [2]. Using tools originating from the Random Matrix Theory we show that the significant changes in the statistics of the traffic data can be explained applying equilibrium statistical physics of interacting particles. PACS numbers: 89.40.-a, 05.20.-y, 45.70.Vn
