A Multiresolution Approach to Render 3D Models
IOS Press (2013)Image synthesis techniques are present in a wide range of applications as they leverage the amount of information required for creating realistic visualizations. For fast hardware rendering they usually employ a triangle-based ... -
Photon Counting 3-D Object Recognition Using Digital Holography
Institute of Electrical and Electronics Engineers (IEEE) (2013)We present an analysis of the recognition performance of 3-D objects reconstructed from digital holograms recorded under photon counting conditions. The digital holograms are computed by applying four-step phase-shifting ...

Importance of habitat heterogeneity and biotic processes in the spatial distribution of a riparian herb (Carex remota L.): a point process approach
Springer (2013-01)This study attempts to understand the dependence on abiotic factors and on the biotic process of the population development. We used three spatial point process models (Poisson, Area-Interaction and shot-noise Cox processes) ...

A universal kriging approach for spatial functional data
Springer (2013-02)In a wide range of scientific fields the outputs coming from certain measurements often come in form of curves. In this paper we give a solution to the problem of spatial prediction of non-stationary functional data. We ...

On a class of non-stationary, compactly supported spatial covariance functions
Springer-Verlag (2013-02)Globally supported covariance functions are generally associated with dense covariance matrices, meaning severe numerical problems in solution feasibility. These problems can be alleviated by considering methods yielding ...

Band selection in spectral imaging for non-invasive melanoma diagnosis
Optical Society of America (2013-03-04)A method consisting of the combination of the Synthetic Minority Over-Sampling TEchnique (SMOTE) and the Sequential Forward Floating Selection (SFFS) technique is used to do band selection in a highly imbalanced, small ...

Geometric approach to non-relativistic quantum dynamics of mixed states
AIP Publishing LLC (2013-05)In this paper we propose a geometrization of the non-relativistic quantum mechanics for mixed states. Our geometric approach makes use of the Uhlmann's principal fibre bundle to describe the space of mixed states and as a ...

Smooth shadow boundaries with exponentially-warped gaussian filtering
Elsevier (2013-05)Shadow mapping is widely used in computer graphics for efficiently rendering shadows in real-time applications. Shadow maps cannot be filtered as regular textures, thus their limited resolution can cause severe shadow map ...

Simplification method for textured polygonal meshes based on structural appearance
Springer-Verlag (2013-05)This paper proposes an image-based simplification method for textured triangle meshes that preserves the structural appearance of textured models. Models used in interactive applications are usually composed of textured ...

Gait-based Gender Classification Considering Resampling and Feature Selection
Engineering and Technology Publishing (2013-06)Two intrinsic data characteristics that arise in many domains are the class imbalance and the high dimensionality, which pose new challenges that should be addressed. When using gait for gender classification, benchmarking ...

Similarity measures of conditional intensity functions to test separability in multidimensional point processes
Springer-Verlag (2013-07)Separability in the context of multidimensional point processes assumes a multiplicative form for the conditional intensity function. This hypothesis is especially convenient since each component of a separable process may ...

Generation of programmable 3D optical vortex structures through devil’s vortex-lens arrays
The Optical Society (OSA) (2013-08)Different spatial distributions of optical vortices have been generated and characterized by implement- ing arrays of devil’s vortex lenses in a reconfigurable spatial light modulator. A simple design procedure assigns the ...

On wavelet-based energy densities for spatial point processes
Springer (2013-08)A spatial point process can be considered a random measure and therefore represented as a countable sum of Delta Dirac measures concentrated at some points of the process. Applying a two-dimensional continuous wavelet ...

A note on smoothness measures for space-time surfaces
Springer Verlag (2013-09)The differentiability of a random field has a direct relationship with the differentiability of its covariance function. We review the concept of differentiability of space–time covariance models and random fields, and its ...

Volume growth of submanifolds and the Cheeger isoperimetric constant
American Mathematical Society (2013-10)We obtain an estimate of the Cheeger isoperimetric constant in terms of the volume growth for a properly immersed submanifold in a Riemannian manifold which possesses at least one pole and sectional curvature bounded from above.

A spatio-temporal Poisson hurdle point process to model wildfires
Springer (2013-11)Wildfires have been studied in many ways, for instance as a spatial point pattern or through modeling the size of fires or the relative risk of big fires. Lately a large variety of complex statistical models can be fitted ...

Unsupervised colour image segmentation by low-level perceptual grouping
Springer (2013-11)This paper proposes a new unsupervised approach for colour image segmentation. A hierarchy of image partitions is created on the basis of a function that merges spatially connected regions according to primary perceptual ...
