Abstract: We are interested in this article in recovering line segment (or planar) cracks from incomplete boundary measurements. Most recovery algorithms, and especially fast ones based on the reciprocity gap, however need a full set of boundary data, which compels us to extending the available data prior to achieving recovery. Both the extension and recovery problems being severely ill posed, their stacking might drive the whole process to a blowing up, unless the instabilities are properly handled. Numerical results actually prove the so-built composite algorithm to hold good accuracy and robustness features.
