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...
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
Investigation of the errors in SDSS proper-motion measurements using samples of quasars
2011/10/17
We investigate in detail the probability distribution function (pdf) of the proper-motion measurement errors in the SDSS+USNO-B proper-motion catalog of \citet{mun04} using clean quasar samples. The p...
Galactic S Stars: Investigations of Color, Motion, and Spectral Features
Galactic S Stars: Investigations Motion Spectral Features
2011/10/12
Known bright S stars, recognized as such by their enhanced s-process abundances and C/O ratio, are typically members of the asymptotic giant branch (AGB) or the red giant branch (RGB). Few modern digi...
PHOTOGRAPHIC ZENITH TUBE OBSERVATIONS TO IMPROVE HIPPARCOS PROPER MOTION IN DECLINATION OF SOME STARS
Astrometry-Reference systems
2009/3/3
in declination for some HIPPARCOS stars are presented. A long
series of optical observations of these stars observed with Photographic Zenith Tubes
(PZT) are used. The HIPPARCOS ESA mission (ESA 199...
