Estimation of Optimal PDE-Based Denoising in the SNR Sense
Image denoising nonlinear diffusion signal-tonoise ratio (SNR) total-variation variational image processing
2010/1/7
This paper is concerned with finding the best partial differential equation-based denoising process, out of a set of possible ones. We focus on either finding the proper weight of the fidelity term in...

Improving motion estimation by accounting for local image distortion
Cardiac elastography Motion estimation Image transformation
2010/1/6
Cardiac elastography is a useful diagnostic technique for detection of heart function abnormalities, based on analysis ofechocardiograms. The analysis of the regional heart motion allows assessing the...
An Efficient Estimation Method for Reducing the Axial Intensity Drop in Circular Cone-Beam CT
Estimation Method Circular Cone-Beam CT
2009/9/4
Reconstruction algorithms for circular cone-beam (CB) scans have been extensively studied in the literature. Since insufficient data are measured, an exact reconstruction is impossible for such a geom...
Estimation of Extracellular Volume by Simultaneous Instrumentation of Bioimpedance and Plasma Colloid Osmotic Pressure
bioimpedance colloid osmotic pressure dialysis patient dry weight, extracellular volume
2009/6/9
Extracellular fluid volume can be roughly estimated using the approximate electric resistivity calculated using only the set fluid removal quantity and the measured impedance of each body part in ECUM...
Estimation of current density distribution under electrodes for external defibrillation
current density distribution electrodes external defibrillation
2010/3/1
The current density distribution non-uniformity of circular electrodes is about 30% less than that of square-shaped electrodes. The use of an interface layer of intermediate resistivity, comparable to...
