  • upper body pose recognition based on Circular Cylindrical Coordinate system
    Journal of KIISE:Software and Applications, 2012
    Co-Authors: Jaewan Park, Daehyeon Song, Chilwoo Lee
    Abstract:

    In this paper, we propose how to recognize upper-body poses using depth image based cylindric Coordinate system. In order to recognize the pose, we configure the cylindric Coordinate system belong to body features and the distance which is configured from camera to center of body using the pose candidate images. And we extract vectors of the features using depth informations which are presented brightness values. The extracted vectors are mapped to radial feature space and classified pose pattern. And the pose patterns are learned using average of the feature points and recognized the poses by comparing pre-defined pose patterns using euclidean distance. In this paper, in order to classify the features of the upper poses, we proposed method which can be composed of the poses and the upper pose patterns. The poses and the pose patterns are composed by using distance and angle from the center of the Cylindrical Coordinate system. In this paper, we purpose to extract effective pose information using simple operation applying dynamic Cylindrical model to pose candidate images.

  • Physical fields of hydroacoustic antenna consisting of the angle of the horn and the piezoceramic transducer with a circumferential polarization
    Киев, 2014
    Co-Authors: Гусак, З. Т., Лейко, А. Г., Лейко, О. Г., Gusak Z. T., Leiko A. G.
    Abstract:

    Розглянута гідроакустична антена, що складається з кругового рупорного відбивача м'якого типу і розташованого в його гирлі циліндричного п'єзокерамічного випромінювача з обводовою поляризацією. При цьому конструктивне виконання випромінювача може мати силовий або компенсований варіанти. Методами зв'язаних полів і часткових областей вирішена задача і отримані аналітичні вирази, що описують фізичні поля рупорної антени – акустичні, механічні і електричні. Ці поля представлені у вигляді розкладень у ряди по хвильовим функціям кругової циліндричної системи координат з невідомими коефіцієнтами розкладів, що визначаються із граничних умов і умов спряження полів на межах розділу областей. Рішення зведено до нескінченної системи лінійних алгебраїчних рівнянь.Considered hydroacoustic antenna consisting of the angle of the horn reflector soft type and placed in his mouth Cylindrical piezoceramic transducer with a circumferential polarization. Thus the design of the transmitter can be power or compensating type. The problem was solved by methods related fields and analytical expressions describing the physical fields of the horn antenna – acoustic, mechanical and electrical. These fields are presented in the form of expansions in series of the wave functions of the Circular Cylindrical Coordinate system with unknown expansion coefficients which are determined from the boundary conditions and the matching conditions at the interfaces between fields areas. Solution is reduced to an infinite system of linear algebraic equations.Рассмотрена гидроакустическая антенна, состоящая из уголкового рупорного отражателя мягкого типа и расположенного в его устье цилиндрического пьезокерамического излучателя с окружной поляризацией. При этом конструктивное исполнение излучателя может иметь силовой или компенсированный варианты. Методами связанных полей и частичных областей решена задача и получены аналитические выражения, описывающие физические поля рупорной антенны – акустические, механические и электрические. Эти поля представлены в виде разложений в ряды по волновым функциям круговой цилиндрической системы координат с неизвестными коэффициентами разложений, определяемыми из граничных условий и условий сопряжения полей на границах раздела областей. Решение сведено к бесконечной системе линейных алгебраических уравнений
