This work presents the development of Software (SOFA hereafter) for morphological quality assurance in GEM-foils (electrodes of a GEM-like detector) through the analysis of high resolution images. SOFA Software for Foils Analysis) performs an automated measurement of the holes geometry presented in the GEM-foils, in order to detect and quantify different defects far from their ideal geometric characteristics. This work underlines the speed, automation and precision of SOFA regarding quality visual inspection used in manufacturing process of GEM-foils. SOFA is a R\&D tool, because its measurements allow establishing relation between GEM-foils defects and GEM-like detector performance.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
