Compressive holography with phase-structured illumination
(IEEE, 2015-06)
We describe several approaches to perform digital
holography with single-pixel detection by using phase-structured
illumination and compressive sensing. Single-pixel imaging
works by sampling the scene ...
Assessing local differences between the spatio-temporal second-order structure of two point patterns occurring on the same linear network
(2021)
We introduce Local Indicators of Spatio-Temporal Association (LISTA) functions on linear networks and use them to build a statistical test for local second-order structure. This allows to identify differences in the ...
All-fiber incoherent frequency-to-time mapping method for microwave signal generation with baseband transmission and multicasting support
(Elsevier, 2008)
We present a proof-of-principle experiment for achieving simultaneous distribution of baseband radio-frequency data and up-conversion with broadcasting support over a passive optical network. The technique is based on an ...
Flat-top ultra-wideband photonic filters based on mutual coherence function synthesis
(Elsevier, 2008)
A novel all-incoherent optical circuit that allows for band-pass microwave-photonic filter design is presented and verified through numerical simulation. In contrast to conventional spectrum-sliced optical architectures ...
Second-order smoothing of spatial point patterns with small sample sizes: a family of kernels
(Springer Verlag, 2015-01)
We consider kernel-based non-parametric estimation of second-order product densities of spatial point patterns. We present a new family of optimal and positive kernels that shows less variance and more flexibility than ...
Spatial Cox processes in an infinite-dimensional framework
(Sociedad de Estadística e Investigación Operativa (Spanish Society of Statistics and Operations Research)Springer, 2021-04-29)
We introduce a new class of spatial Cox processes driven by a Hilbert-valued randomlog-intensity. We adopt a parametric framework in the spectral domain, to estimateits spatial functional correlation structure. Specifically, ...
Separable soft shadow mapping
(Springer, 2015-02)
We propose an efficient technique for rendering visually plausible real-time soft shadows in screen space. First, we propose a novel blocker estimation technique based on a separable filter. Second, our technique performs ...
Normalized global alignment for protein sequences
(Elsevier, 2011)
Global alignment is used to compare proteins in different fields, for example in phylogenetic research. In order to reduce the length and composition dependence of global alignment scores, Z-score is computed with a ...
On the effectiveness of preprocessing methods when dealing with different levels of class imbalance
(Elsevier, 2012)
The present paper investigates the influence of both the imbalance ratio and the classifier on the performance of several resampling strategies to deal with imbalanced data sets. The study focuses on evaluating how learning ...
Single-pixel imaging through turbid media by combining a programmable light source and a DMD
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2023-03-15)
Imaging through turbid media remains a relevant topic in biomedical imaging. In this contribution, we propose the combination of frequency domain imaging (SFDI) and single-pixel imaging (SPI) to image objects hidden by a ...
