Reconstruction of undersampled dynamic images by modeling the motion of object elements
(2007)
Dynamic MRI is restricted due to the time required to obtain enough data to reconstruct the image sequence. Several undersampled reconstruction techniques have been proposed to reduce the acquisition time. In most of these ...
Dynamics of Pinus wood prices for different timber assortments: comparison of stochastic processes
(Cirad-centre Cooperation Int Recherche Agronomique Pour, 2022-01-01)
Understanding the dynamics of market prices for Pinus wood is a prerequisite for strategic decisions concerning forest investment plans since, in terms of the market, the exogenous risk to a project depends on timber ...
Simultaneous Motion Detection and Background Reconstruction with a Conditional Mixed-State Markov Random Field
(Springer, 2011-09)
In this work we present a new way of simultaneously solving the problems of motion detection and background image reconstruction. An accurate estimation of the background is only possible if we locate the moving objects. ...
Maximum likelihood estimation of cardiac fiber bundle orientation from arbitrarily spaced diffusion weighted images
(Elsevier, 2017)
We propose an estimation scheme for local fiber bundle direction in the left ventricle directly from gray values of arbitrarily spaced cardiac diffusion weighted images (DWI). The approach is based on a parametric and ...
Power laws and inverse motion modelling: Application to turbulence measurements from satellite images
(Wiley Blackwell Publishing, Inc, 2012-01)
In the context of tackling the ill-posed inverse problem of motion estimation from image sequences, we propose to introduce prior knowledge on flow regularity given by turbulence statistical models. Prior regularity is ...
Robust estimation of 3D trajectories from a monocular image sequence
(JOHN WILEY & SONS INC, 2002)
This article describes a new method for object trajectory estimation that uses sequences of images taken from a monocular camera. The method integrates a Kalman filter to estimate the three-dimensional (3D) parameters of ...
