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…

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…
