Sampling and Reconstruction of Surfaces and Higher Dimensional Manifolds
Image sampling Image reconstruction Geometric approach Fat triangulation Image manifolds
2010/1/8
We present new sampling theorems for surfaces and higher dimensional manifolds. The core of the proofs resides in triangulation results for manifolds with boundary, not necessarily bounded. The method...
Geometric Sampling of Manifolds for Image Representation and Processing
Geometric Sampling Manifolds Image Representation and Processing
2010/1/8
It is often advantageous in image processing and computer vision to consider images as surfaces imbedded in higher dimensional manifolds. It is therefore important to consider the theoretical and appl...
The Farthest Point Strategy for Progressive Image Sampling
Farthest Point Strategy Progressive Image Sampling
2010/1/7
A new method of farthest point strategy (FPS) for progressive image acquisition—an acquisition process that enables an approximation of the whole image at each sampling
stage—is presented. Its main a...

2009/12/30
In order to compare sampling efficiencies of total and inhalable dust methods, three airborne dust sampling systems , 7-Hole sampler , close and open face filter cassette were compared side-by-side , ...
A MORE RATIONAL METHOD FOR SAMPLING OF AIRBORNE FIBROCENIC DUST IN EPIDEMIOLOGY OF PNEUMOCONIOSES
Respirable dust Pneumoconioses Impactor Occupational Health
2009/12/30
Current sampling instruments of respirable dust (RD) may over estimate the inhaled dose by up to 400% depending on the size distribution of airborne dust. This limitation and the practice of assigning...
