Total generalized variation inversion for ERT inversion, using a modified version of IP4DI code, for Matlab. Due to some old dependencies in the version of IP4DI I was working with, it will not run in Matlab versions newer than 2011a. I ahve not tested old
This software allows the 2.5D inversion of ERT data using TGV, l2 and TV (l1) regularisation methods. It is based on the versatile ERT and IP inversion software IP4DI, for single lines of surface electrodes. TGV inversion favours piecewise affine (blocky regions separated by linear gradients) behaviour, allowing both smooth and sharp contrasts to be captured by the inversion.
