Generalized pattern matching using orbit decomposition

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2003

Motion estimation, motion detection and tracking invariably require finding a particular pattern in a set or sequence of images. The task involves finding appearances of a given pattern in an image under various transformations and at various locations. This process is of very high time complexity since a search must be implemented both in the transformation domain and in the ...


Impedance calculations for traveling-wave gyrotrons operating at harmonics of the cyclotron frequency in circular and rectangular overmoded waveguides

1982 International Electron Devices Meeting, 1982

The interaction impedance of traveling-wave gyrotrons has recently been defined for harmonics of the cyclotron frequency. The interaction impedance is a function of waveguide geometry, mode numbers, orbit radius, and orbit location within the guide. This paper treats all of the electromagnetic harmonics in all circular and rectangular waveguide modes. Analytic expressions for the magnitude of the interaction impedance are ...

  • Generalized pattern matching using orbit decomposition

    Motion estimation, motion detection and tracking invariably require finding a particular pattern in a set or sequence of images. The task involves finding appearances of a given pattern in an image under various transformations and at various locations. This process is of very high time complexity since a search must be implemented both in the transformation domain and in the spatial domain. Contributing to this complexity is the chosen distance metric that measures the similarity between patterns. The Euclidean distance, for example, may change drastically when a small transformation is applied to the pattern. Applying a different metric distance might be advantageous, though at the expense of loosing the norm structure of the Euclidean space. In this work we present a new method for fast search in the transformation domain, which can also be applied in metric spaces. The method is based on recursive decomposition of the transformation domain, and a rejection scheme, which enables the process to quickly reject as irrelevant large percentages of this decomposition.

  • Impedance calculations for traveling-wave gyrotrons operating at harmonics of the cyclotron frequency in circular and rectangular overmoded waveguides

    The interaction impedance of traveling-wave gyrotrons has recently been defined for harmonics of the cyclotron frequency. The interaction impedance is a function of waveguide geometry, mode numbers, orbit radius, and orbit location within the guide. This paper treats all of the electromagnetic harmonics in all circular and rectangular waveguide modes. Analytic expressions for the magnitude of the interaction impedance are developed, and are evaluated by both numerical and exact analytic methods. Results show that the impedance of any single harmonic over the waveguide cross section may be expressed as a linear combination of a small number of simple entire-domain functions, the corresponding coefficients of which are directly calculated by numerical integration. Since the coefficients of a particular harmonic are expressible as a function of only two variables, a three-dimensional plot clearly illustrates the optimum combination of parameters. Contours of interaction impedance as a function of position in the waveguide are shown and optimum geometrical arrangements to achieve highest impedance values for particular harmonics are demonstrated.

  • Look angle contours of small transportable satellite earth stations for Arab Gulf countries

    The authors present look angle contours over Arab Gulf countries to enable engineers and technicians to point any earth station directly (without any calculations) towards a given satellite in the geostationary orbit. Contours over Arab Gulf countries have been presented for ARABSAT and SABS satellite systems. These contour plots could be used efficiently for transportable and television receive-only earth stations to be deployed anywhere in rural and isolated areas. The proposed method could generally be applied to any area served by a given satellite.<<ETX>>

  • Exact Calculation of Nonlinear Orbit Properties of a Synchrotron

    The trajectory of a particle in an arbitrary guide field can be computed as accurately as desired by numerical integration. This "measured" trajectory can then be fit with the phase-amplitude relation describing betatron oscillations, suitably generalized to account for nonlinear effects. Information about closed on- and off-momentum orbits, as well as the frequencies of small oscillations about them, can be obtained from such fits. Thus one can compute chromaticities exactly, among other things.

  • Determination of the Best Coverage Area for Receiver Stations of LEO Remote Sensing Satellites

    During receiving data broadcasted by remote sensing satellites, ground stations are capable of gathering data up to a restricted area around the station location; this area is called receiving coverage area and its size is a critical parameter defining station performance. Receiving Coverage Area (RCA) is affected by various parameters such as satellite altitude, minimum elevation angle of receiver antenna, environmental restrictions of visibility in angles close to horizon line and economical concerns. The purpose of this paper is to study the impact of each of these parameters in RCA and also to better introduce the practical restrictions on way of designers deciding to extend the size of receiving coverage area in station. Having these pieces of information, the paper has obtained a best compromise between meeting requirements and construction cost of a Remote Sensing Satellite (RSS) station. The presented article is the result of one-year continuous effort conducted in ITRC Satellite Group for the design of remote sensing ground stations, considering the appropriate coverage area which is one of the most significant targets.

  • Comparative analysis of frequency-doubling gyro-TWTs operating at different cyclotron harmonics

    In this paper we present the results of analysis of two frequency-doubling gyro-TWT schemes. Both of them are based on the doubling of the signal frequency. They are different in the cyclotron resonance harmonics used in each stage. In the first configuration, the input waveguide operates at the fundamental cyclotron resonance while the output waveguide operates at the second harmonic; a so-called 1-2 scheme. In the second configuration, the input waveguide operates at the second cyclotron harmonic while the wave excited in the output waveguide at the second harmonic of the signal frequency interacts with electrons at the fourth cyclotron harmonic (2-4 scheme).

  • Geometric aspects of polar and near polar circular orbits for the use of intersatellite links for global communication

    In this paper the polar and the near polar circular orbit constellations are examined for the use of intersatellite links. We have the following definitions: the polar orbit has an inclination angle of exactly 90 deg and the near polar orbit constellation has an inclination angle between 80 deg and 100 deg but not equal to 90 deg. We present the exact equations for the intersatellite distance, the azimuth and elevation angles between two satellites. These equations are applied to an example system, a system that is using intersatellite links and that is based on the circular polar and near polar orbit constellation. To establish an intersatellite link, the distance between two satellites should be small and the variation of the azimuth and elevation angle should also be small. It is shown how a change of the inclination angle influences the whole orbit constellation in order to provide full coverage of the Earth and it is shown how the inclination angle between two satellites on adjacent orbital planes influences the distance, the azimuth, and the elevation angle difference.

  • Slow Extraction from FFAG Accelerators

    The results of earlier analytical calculations on the slow extraction of particles from an alternating gradient accelerator are applied to the special case of a fixed field alternating gradient accelerator.
