Point Morphology

A new approach to the morphological analysis of point clouds, based on a new structuring element model, a robust projective formulation of the operators, and a specific adaptive sampler. The method is applied to geometry and topology manipulation, including medial axis sampling, hysteresis shape filtration, and topological simplification.

Floating Scale Surface Reconstruction

Introducing a novel, virtually parameter-free method for surface reconstruction from oriented, scale-enabled point samples. The approach constructs an implicit function as the sum of compactly supported basis functions. The final surface is extracted as the zero-level set of the implicit function.

Continuous Projection for Fast L1 Reconstruction

Continuous locally optimal projection (CLOP) is a novel analytic projection operator that allows for fast L1 reconstruction of dynamic point sets at interactive frame rates. It uses a continuous reformulation of the discrete weighted locally optimal projection (WLOP) operator, which it outperforms by up to an order of magnitude.

Flower Modeling Via X-Ray Computed Tomography

This paper presents a novel flower-modeling technique that utilizes X-ray computed tomography and real-world flowers. The method approximates a flower by key primitives, a shaft, and a sheet, and semi-automatically fits them to flower CT volume by using new active curve and surface models.

k-d Darts: Sampling by k-Dimensional Flat Searches

This paper extends the concept of point sampling to hyperplane sampling: lines, planes, etc. Samples are axis-aligned yet unbiased. The paper demonstrates high-dimensional applications in disk packing, rendering, and failure analysis.
