MEASURING COMPLETE GROUND-TRUTH DATA AND ERROR ESTIMATES FOR REAL VIDEO SEQUENCES, FOR PERFORMANCE EVALUATION OF TRACKING, CAMERA POSE AND MOTION ESTIMATION ALGORITHMS
Vision robotics tracking navigation registration
2015/8/14
Fundamental tasks in computer vision include determining the position, orientation and trajectory of a moving camera relative to an
observed object or scene. Many such visual tracking algorithms hav...
On the algorithms of radiative cooling in semi-analytic models
semi-analytic models galaxy
2014/12/22
We study the behaviour of multiple radiative cooling algorithms implemented in six Semi-Analytic Models (SAMs) of galaxy formation, including a new model we propose in this paper. We use versions of t...

2010/11/16
Gyrosynchrotron (GS) emission of charged particles spiraling in magnetic fields plays
an exceptionally important role in astrophysics. In particular, this mechanism makes a dominant
contribution to ...
Genetic algorithms and the analysis of SnIa data
Genetic algorithms the analysis of SnIa data
2010/11/12
The Genetic Algorithm is a heuristic that can be used to produce model independent solutions to an optimization problem, thus making it ideal for use in cosmology and more specifically in the analysis...
Libpsht - algorithms for efficient spherical harmonic transforms
Instrumentation and Methods for Astrophysics (astro-ph.IM) Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
Libpsht (or "library for Performant Spherical Harmonic Transforms") is a collection of algorithms for efficient conversion between spatial-domain and spectral-domain representations of data defined on...
Evaluating the Magnetorotational Instability's Dependence on Numerical Algorithms and Resolution
turbulence MHD methods numerical accretion discs instabilities
2010/3/9
We have studied saturated, MRI-driven turbulence using three-dimensional, isothermal simulations with resolutions that extend from 64 to 192 zones in each direction. The simulations were performed wit...
