Digitization and Management of the Archive of the Neue Zürcher
Zeitung (NZZ)
The Neue Zürcher Zeitung (NZZ) is one of Europe's leading and
oldest newspaper publishing houses. Its archive contains all of the
articles it has ever published, from the first edition (in 1780) until
the present day. The archive extends further back in history than
almost any other press archive in the world.
Up until now, however, accessing the archive, has been cumbersome. For
the period from 1780 to 1871, there is not even an index to help
search for articles on particular topics. The archivists have to leaf
through every issue one by one, or manually place the microfilms,
which have been made of every volume, into the microfilm reader, and
then look through them.
On the occasion of its 225th anniversary, and set against this
backdrop, the history-conscious publishing house decided to make
available its archive in digital form. The digital newspaper archive
will make it possible for multiple user groups to perform rapid and
precise online searches for relevant newspaper articles.
The newspaper pages are to be presented on the Internet as individual
pages, and preferably as full texts. Users enter keywords via an
Internet browser and will be able to jump to the relevant position in
the digitized newspaper page within seconds.
Two million pages of newsprint documented on 1,500 microfilms will be
digitized, and prepared for automatic access. Microfilmed pages whose
quality does not suffice for digitization will be re-photographed. The
digitization quality will be high enough for both the screen image of the
Internet page and for reproductions of newspaper pages.
This task requires the application of the newest technologies in the
fields of digitization, image processing and optical character
recognition (OCR).

PhD Thesis
Automatische Bildfolgenanalyse mit statistischen Mustererkennungsverfahren
In this thesis new methods for the automatic recognition of the content of
image sequences are presented. Solutions to the following video sequences
analysis tasks are developed: temporal decomposition of an image sequence
into scenes and classification of the scenes, and the recognition of people
and their movements in the image sequence. The temporal segmentation of a
image sequence and the classification of the segments can be used for image
sequences with a given content structure, like broadcast news. The image
sequences have a defined chronology of scenes, which belong to certain
content classes. The content classes and their chronology are represented by
nested Hidden Markov models during the recognition. Another application of
the Hidden Markov Modells are the classification of movements of objects in
the image sequence. The recognition of human gestures for the application of
human-computer-interaction is investigated. The recognition system is
capable of recognizing a set of pre-defined gestures that are performed in
the viewing area of a camera. The system is able to identify undefined
movements and can distinguish them from the gestures. The final task is
recognizing people visible in image sequences. The recognition of the people
is done by recognizing their faces. The indexing of the faces is composed of
the two sub-tasks: detection of the faces and recognition of the faces. It
is shown that the face-based video indexing can be used to find known
persons in the image sequence as well as to group the people in the sequence
unsupervised.
