Multiscale Graph-Cut for 3D Segmentation of Compact Objects

The article is a step forward towards improving image segmentation using a popular method called Graph-Cut. We focus on optimizing the algorithm for processing data, in which the target object occupies only a small portion of the total volume. We propose a twostep procedure. A...

Reconstruction of Cross-Correlations with Constant Number of Deterministic Samples

Optimal fusion of estimates that are computed in a distributed fashion is a challenging task. In general, the sensor nodes cannot keep track of the cross-correlations required to fuse estimates optimally. In this paper, a novel technique is presented that provides the means to ...

Asymptotic relation for zeros of cross-product of Bessel functions and applications

Let $a_{\nu,k}$ be the $k$-th positive zero of the cross-product of Bessel functions $J_\nu(R z) Y_\nu(z) - J_\nu(z) Y_\nu(R z)$, where $\nu\geq 0$ and $R>1$. We derive an initial value problem for a first order differential equation whose solution $\alpha(x)...

Modelovanie regionálneho tiažového poľa z meraní družicovej misie GOCE

In this contribution we discuss a regional recovery of gravity disturbances at the mean geocentric sphere approximating the Earth over the area of Central Europe from satellite gravitational gradients. The main aim of the presented study is to investigate three numerical approaches for&...

Cognitive impairment measured by event-related potentials during early and late postoperative period following intravenous or inhalation anaesthesia

This study investigated modification in cognitive function following inhalation (IA) and total intravenous (TIVA) anaesthesia measured using auditory ERPs (Event Related Potentials). Methods : Auditory ERPs examination with N1, P3a and P3b component registration was carried out one day before sur...
