Comparison of terrain corrections based on the point source and line source DC methods
Frontiers in Earth Science, 2022 In the direct current (DC) exploration method, topographic relief distorts the apparent resistivity curve. To eliminate effects of terrain fluctuations, two undulating terrains comprising valleys and ridges were investigated in the present study.

On the duality of the potential method and the point source method in inverse scattering probelms
Journal of Integral Equations and Applications, 2009 The authors show that two optimization methods for the scattering problem for the reduced wave equation are duals of each other. Both methods use a test domain \(G\) and find approximations to the scattered wave in \({\mathcal R}^m \backslash G\). One method involves finding the source on the unit sphere giving the fundamental solution on \(\partial G\)

Firedec: a two-channel finite-resolution image deconvolution algorithm
, 2016 We present a two-channel deconvolution method that decomposes images into a parametric point-source channel and a pixelized extended-source channel. Based on the central idea of the deconvolution algorithm proposed by Magain, Courbin & Sohy (1998), the ...
