Mumford-Shah regularization in electrical impedance tomography with complete electrode model
Jyrki Jauhiainen, Aku Seppänen, Tuomo Valkonen
In electrical impedance tomography, we aim to solve the conductivity within a target body through electrical measurements made on the surface of the target. This inverse conductivi…
Non-planar sensing skins for structural health monitoring based on electrical resistance tomography
Jyrki Jauhiainen, Mohammad Pour-Ghaz, Tuomo Valkonen +1
Electrical resistance tomography (ERT) -based distributed surface sensing systems, or sensing skins, offer alternative sensing techniques for structural health monitoring, providin…
Relaxed Gauss-Newton methods with applications to electrical impedance tomography
Jyrki Jauhiainen, Petri Kuusela, Aku Seppänen +1
As second-order methods, Gauss--Newton-type methods can be more effective than first-order methods for the solution of nonsmooth optimization problems with expensive-to-evaluate sm…
Gaussian process regression for forest attribute estimation from airborne laser scanning data
Petri Varvia, Timo Lähivaara, Matti Maltamo +2
While the analysis of airborne laser scanning (ALS) data often provides reliable estimates for certain forest stand attributes -- such as total volume or basal area -- there is sti…
Open 2D Electrical Impedance Tomography data archive
Andreas Hauptmann, Ville Kolehmainen, Nguyet Minh Mach +3
This document reports an Open 2D Electrical Impedance Tomography (EIT) data set. The EIT measurements were collected from a circular body (a flat tank filled with saline) with vari…
Optimizing electrode positions in electrical impedance tomography
Nuutti Hyvönen, Aku Seppänen, Stratos Staboulis
This work considers finding optimal positions for the electrodes within the Bayesian paradigm based on available prior information on the conductivity; the aim is to place the elec…
Simultaneous reconstruction of outer boundary shape and admittivity distribution in electrical impedance tomography
Jérémi Dardé, Nuutti Hyvönen, Aku Seppänen +1
The aim of electrical impedance tomography is to reconstruct the admittivity distribution inside a physical body from boundary measurements of current and voltage. Due to the sever…
