Geometry-aware direction field processing [PDF]

open access: yesACM Transactions on Graphics, 2009
Many algorithms in texture synthesis, nonphotorealistic rendering (hatching), or remeshing require to define the orientation of some features (texture, hatches, or edges) at each point of a surface. In early works, tangent vector (or tensor) fields were used to define the orientation of these features.

Monte Carlo geometry processing [PDF]

open access: yesACM Transactions on Graphics, 2020
This paper explores how core problems in PDE-based geometry processing can be efficiently and reliably solved via grid-free Monte Carlo methods. Modern geometric algorithms often need to solve Poisson-like equations on geometrically intricate domains.

Monitoring the Petermann Ice Island with TanDEM-X [PDF]

open access: yes, 2012
This paper presents the processing of TanDEM-X acquisitions for the monitoring of the topography of the Petermann ice island. In this particular case the area under study is continuously moving and the acquisition geometry is changing, so the processing ...

Area collapse algorithm computing new curve of 2D geometric objects

open access: yesGeodesy and Cartography, 2017
The processing of cartographic data demands human involvement. Up-to-date algorithms try to automate a part of this process. The goal is to obtain a digital model, or additional information about shape and topology of input geometric objects.

Development of a technological process for the restoration of piston pins using deforming broaching

open access: yesПроблеми трибології, 2022
The article discusses the technological process of restoring the geometric dimensional accuracy of piston pins of internal combustion engines (ICE) due to the expansion of the internal hole by a deforming element.

Real-time programmable acoustooptic synthetic aperture radar processor [PDF]

open access: yes, 1988
The acoustooptic time-and-space integrating approach to real-time synthetic aperture radar (SAR) processing is reviewed, and novel hybrid optical/electronic techniques, which generalize the basic architecture, are described.

3D scanning and geometry processing techniques for customised hand orthotics: an experimental assessment

open access: yesVirtual and Physical Prototyping, 2018
In the field of rehabilitation, the 3D scanning of body parts can be considered a crucial starting point for subsequent 3D model design of customised devices, especially when additive manufacturing techniques are involved in their production.

Validating a new methodology for optical probe design and image registration in fNIRS studies [PDF]

open access: yes, 2014
Functional near-infrared spectroscopy (fNIRS) is an imaging technique that relies on the principle of shining near-infrared light through tissue to detect changes in hemodynamic activation. An important methodological issue encountered is the creation of
