PROBABILITY CURRENT AND TRAJECTORY REPRESENTATION

by A. Bouda , 2000
"... A unified form for real and complex wave functions is proposed for the stationary case, and the quantum Hamilton-Jacobi equation is derived in the three-dimensional space. The difficulties which appear in Bohm’s theory like the vanishing value of the conjugate momentum in the real wave function case ..."

Parametric Trajectory Representations for Behaviour Classification

by Rowland R. Sillito, Robert B. Fisher , 2009
"... This paper presents an empirical comparison of strategies for representing motion trajectories with fixed-length vectors. We compare four techniques, which have all previously been adopted in the trajectory classification literature: least-squares cubic spline approximation, the Discrete Fourier Tra ..."

Transform, Chebyshev polynomial approximation, and the Haar wavelet transform. We measure the class separability of five different trajectory datasets- ranging from vehicle trajectories to pen trajectories- when described in terms of these representations. Results obtained over a range of dimensionalities

El objetivo de este proyecto es el estudio, desarrollo y evaluación de un sistema robusto de rep-resentación de trayectorias de objetos para vídeo vigilancia. El sistema debe permitir trabajar de forma flexible con las trayectorias, generando una representación útil para aplicaciones de más alto nivel. La solución propuesta comprende cuatro fases, cada una con un propósito determinado. La primera fase consiste en un algoritmo que se encarga de realizar las tareas necesarias para ex-traer las trayectorias de los objetos en movimiento de los vídeos. La segunda fase o comprende una serie de técnicas destinadas a mejorar y depurar la información obtenida en la fase ante-rior. En la tercera etapa, las trayectorias se dividen para facilitar su posterior uso y análisis. Por último, se desarrolla una representación precisa de las trayectorias que también permite la reconstrucción de las trayectorias originales. Para la evaluación del sistema se utilizan dos bases de datos distintas, tratando de incluir los escenarios y situaciones más frecuentes en vídeo vigilancia. Cada técnica utilizada en el sistema se evalúa de manera individual, determinando su eficacia para la consecución del objetivo final. Para la correcta evaluación de algunas partes del proyecto ha sido necesario construir una base

Trajectory Representation Using Sequenced Linear Dynamical Systems

by Kevin R. Dixon, Pradeep K. Khosla - in Proceedings of the IEEE International Conference on Robotics and Automation , 2004
"... In this paper we present a novel approach for representing trajectories using sequenced linear dynamical systems. This method uses a closed-form least-squares procedure to fit a single Linear Dynamical System (LDS) to a simple trajectory. These LDS estimates form the elemental building blocks used t ..."

Extended Version of “The Philosophy of the Trajectory Representation of Quantum Mechanics”

by Edward R. Floyd , 2000
"... The philosophy of the trajectory representation differs with Copenhagen and Bohmian philosophies. The trajectory representation is a strongly causal, nonlocal theory of quantum mechanics that is deterministic. It is couched in a generalized Hamilton-Jacobi formulation. For bound states, each particu ..."

Activity based video content trajectory representation and segmentation

by Tao Xiang, Shaogang Gong - In BMVC , 2004
"... A novel approach is developed to segment continuous CCTV recordings according to the activities captured in the scene. This approach differs from previous approaches which are mostly based on shot change detection and shot grouping. Video content is represented by constructing a cumulative multi-eve ..."

Feature Space Trajectory Representation for Active Vision

by Michael A. Sipe, David Casasent, Leonard Neiberg - In Proc. SPIE , 1997
"... A new feature space trajectory (FST) description of 3-D distorted views of an object is advanced for active vision applications. In an FST, different distorted object views are vertices in feature space. A new eigen-feature space and Fourier transform features are used. Vertices for different adjace ..."

Trajectory Representation in Location-Based Services: Problems and Solution

by Nirvana Meratnia, Rolf A. - Eds.) Proceedings of Fourth International Conference on Web Information Systems Engineering Workshops (WISEW'03 , 2003
"... Recently, much work has been done in feasibility studies on services offered to moving objects in an environment equipped with mobile telephony, network technology and GIS. However, despite of all work on GIS and databases, the situations in which the whereabouts of objects are constantly monitored ..."
