purpose : to investigate the risk factors and causes for blindness in behcet’s disease (bd). methods : in this preliminary retrospective case series we have investigated 27 bd patients (54 eyes), legally blind (vision 0.1 or less) at least in one eye at the last visit (2006), and compared them with 54 eyes of 27 non-blind patients (control group), matched individually and consequently in terms ...

The CSPD-1 y-ray vision system has been constructed for the energy range from 100 keV up to a few MeV, which encompasses most energies of y-ray radiation from the radioactive nuclides of interest t o nuclear facilities. The angular resolution of the system can be varied from about 7" down to 3" FWHM. The energy resolution at 662 keV is 6.8% or 8.9% FWHM depending on which of the two detectors a...

Many real world problems require a degree of exibility that is di cult to achieve using hand programmed algorithms. One such domain is vision-based autonomous driving. In this task, the dual challenges of a constantly changing environment coupled with a real time processing constrain make the exibility and e ciency of a machine learning system essential. This chapter describes just such a learn...

some physical attributes of two common types of iranian garlic cloves (white and pink) were identified and compared. a machine vision system was used to determine three di-mensions and both major and minor projected areas of garlic cloves at a moisture content of 42.4% w. b. the geometric mean diameter and sphericity were calculated, as well as the unit mass and volume of cloves were measured. ...
