The article was aimed at studying the process of learning by local difference threshold when filtering normal white noise. existing algorithms for image processing were analyzed and their advantages disadvantages identified. influence noise on recognition is considered. A method organizing correlator with preprocessing GQP has been developed. dependence average value readings rank CCF (RCCF) GQ...

Owing to the Japanese government plan, U-Japan, which promised to bring about the socalled ‘ubiquitous society’ by 2010, the use of Internet has dramatically increased and accordingly, development of the system through IT networks is thriving. The term ‘ubiquitous society’ became a buzzword, signifying easy access to content on the internet for anybody, anywhere and at any time. Face recognitio...

The Murchison Widefield Array (MWA) is a Square Kilometre Array (SKA) Precursor. The telescope is located at the Murchison Radio–astronomy Observatory (MRO) in Western Australia (WA). The MWA consists of 4096 dipoles arranged into 128 dual polarisation aperture arrays forming a connected element interferometer that cross-correlates signals from all 256 inputs. A hybrid approach to the correlati...

Introduction One critical area of the Molonglo system is the beamformer. The resistive array is custom made and some spares are unavailable for the computer that collects the data. It would be difficult to recover from a failure in either of these components. The use of this beamformer also results in data (beams) that cannot be processed by standard methods in imaging packages such as AIPS++ o...

The three-dimensional (3-D) joint transform correlator is demonstrated with realistic targets. Three-dimensional objects observed by multiple cameras are correlated with a 3-D reference object. The number of cameras and their directions of observation are particularly considered.

This paper explains the realization and the performance of a digital stepping correlator in a wideband radio channel measurement system. Radio channel sounding is based on the estimation of the radio channel by use of maximum length sequence (m-sequence) as an effective sounding signal. Signal is detected using the stepping correlator receiver. The received signal is not converted to the baseba...

We establish a relation between the two-point field strength correlator in QCD and the dual field propagator of an effective dual Abelian Higgs model describing the infrared behaviour of QCD. We find an analytic approximation to the dual field propagator without sources and in presence of quark sources. In the latter situation we also obtain an expression for the static qq̄ potential. Our deriva...
