Alignment of highly resolved time-dependent experimental and simulated crash test data
TL;DR: In this article , a data representation stemming from a discrete Laplace-Beltrami operator is proposed for the comparison of highly resolved experimental data with corresponding simulation data, which enables the identification of the best corresponding simulation among several numerical results, allowing inferring physical quantities that cannot be measured in experiments.

Global Optimisation for Improved Volume Tracking of Time-Varying Meshes
TL;DR: In this article , a temporally global optimisation step is proposed to improve the intermediate results obtained via forward tracking, together with an improved formulation of volume element affinity and a robust means of identifying and removing tracking irregularities, yielding a substantially better model of temporal volume correspondence.

Marching cubes: A high resolution 3D surface construction algorithm
TL;DR: In this paper, a divide-and-conquer approach is used to generate inter-slice connectivity, and then a case table is created to define triangle topology using linear interpolation.

Point Set Registration: Coherent Point Drift
Andriy Myronenko,Xubo Song +1 more
TL;DR: A probabilistic method, called the Coherent Point Drift (CPD) algorithm, is introduced for both rigid and nonrigid point set registration and a fast algorithm is introduced that reduces the method computation complexity to linear.

Synthesis and evaluation of linear motion transitions
Jing Wang,Bobby Bodenheimer +1 more
TL;DR: This article develops methods for determining visually appealing motion transitions using linear blending, and assess the importance of these techniques by determining the minimum sensitivity of viewers to transition durations, the just noticeable difference, for both center-aligned and start-end specifications.

Generalizing motion edits with Gaussian processes
TL;DR: This work shows that it can make motion editing more efficient by generalizing the edits an animator makes on short sequences of motion to other sequences, and predicts frames for the motion using Gaussian process models of kinematics and dynamics.

A comparative study of efficient initialization methods for the k-means clustering algorithm
TL;DR: It is demonstrated that popular initialization methods often perform poorly and that there are in fact strong alternatives to these methods, and eight commonly used linear time complexity initialization methods are compared.
