Das Stadtarchiv München hat seit 2016 ein digitales Archiv in Betrieb und übernimmt seitdem elektronische Unterlagen aus der Stadtverwaltung der Landeshauptstadt und von privater Seite, letzteres aber noch eher selten. Die häufigste Form der digitalen Abgabe sind dabei unstrukturierte Dateisammlungen. Diese können in der Regel nicht ohne Vorarbeit ingestiert und im digitalen Magazin gesichert werden. Der Beitrag möchte zeigen, vor welche Herausforderungen uns unstrukturierte Dateisammlungen bei der Archivierung stellen, und wie wir solche Abgaben im Stadtarchiv München, unterstützt von zahlreichen Tools, im sogenannten PreIngest analysieren, bewerten und für den Ingest aufbereiten. / The Munich City Archives have a digital archive in operation since 2016 and since then take over digital data from the city administration of the state capital and from private sources, although the latters still are rare. The most common form of digital accessions are unstructured file collections. As a rule, these cannot be transferred into the archives’ repository without preparatory work. The article attempts to show the challenges unstructured file collections present us with when archiving, and how we analyze and evaluate such accessions in the Munich City Archives, supported by numerous software-tools, in the so-called pre-ingest and how we prepare them for the ingest.

In the field of face recognition one challenge is to recognize individuals in photographs taken of the person in profile. In this project it was investigated whether 3D face reconstructions could improve the face recognition results in these cases. Images used in the experiments were historical images of persons who lived in Stockholm during the late nineteenth to early twentieth centuries. Additionally, face frontalization algorithms were applied to images taken in profile-view of the person to investigate if this idea could improve the results of 3D face reconstruction of images in profile-view. The results of the experiments showed that using 3D face reconstructions did not improve the results of face recognition. However, in most cases the individuals in the 3D face reconstructions could be recognized. Furthermore, experiments also showed that face frontalization did not improve the results of the 3D face reconstructions of images taken in profile angle. Aside from these results, the thesis demonstrates a, to the best of our knowledge, new approach to evaluate 3D face reconstruction results by using face recognition.
