Automatic image quality assessment as well as image classification onto indoor/outdoor ones are performed by subdivision of image under analysis onto a number of fragments. Detecting overexposed, underexposed, low contrast or normal images is carried out by analyzing luminance histogram of the image and its constituting segments. At the stage of image… (More)
A time- and space-resolved hard x-ray source was developed as a diagnostic tool for imaging underwater exploding wires. A ~4 ns width pulse of hard x-rays with energies of up to 100 keV was obtained from the discharge in a vacuum diode consisting of point-shaped tungsten electrodes. To improve contrast and image quality, an external pulsed magnetic field… (More)
It has been shown by means of calculation and device modeling that the observed subjective pressure of two objects moving toward one another behind a narrow vertical slit corresponds to the pressure of objects retinal projections, induced in its turn by a slowed down tracing. 180e turn of one of the moving objects is also explained by tracing.
Recently, a new high energy proton microscopy facility PRIOR (Proton Microscope for FAIR Facility for Anti-proton and Ion Research) has been designed, constructed, and successfully commissioned at GSI Helmholtzzentrum für Schwerionenforschung (Darmstadt, Germany). As a result of the experiments with 3.5-4.5 GeV proton beams delivered by the heavy ion… (More)
A number of theoretical approaches to the analysis of the parameters of a discharge channel consisting of strongly coupled plasma generated in the process of underwater electrical wire explosion are presented. The analysis is based on experimental results obtained from discharges employing Cu wire. The obtained experimental data included electrical… (More)
