A SCAPE research paper on “Quality assurance for document image collections in digital preservation” will be presented by Reinhold Huber-Mörk and Alexander Schindler (AIT). This paper shows an approach to image based quality assurance for digital image collections based on local descriptor matching. Spatially distinctive local keypoints of contrast enhanced images and robust symmetric descriptor matching are used to calculate affine transformations for image registration. Structural similarity of aligned images is used for quality assessment. The results show, that the approach can efficiently asses the quality of digitized documents including images of blank paper.

Under the title “Structural and visual comparisons for Web page archiving”, Marc Teva Law, Nicolas Thome, Stéphane Gançarski and Matthieu Cord of the UPMC – Sorbonne University propose a Web page archiving system that combines state-of-the-art comparison methods based on the source codes of Web pages, with computer vision techniques. To detect whether successive versions of a Web page are similar or not, their system is based on:
(1) a combination of structural and visual comparison methods embedded in a statistical discriminative model
(2) a visual similarity measure designed forWeb pages that improves change detection,
(3) a supervised feature selection method adapted to Web archiving.
They train a Support Vector Machine model with vectors of similarity scores between successive versions of pages. The trained model then determines whether two versions, defined by their vector of similarity scores, are similar or not. Experiments on real archives validate the approach.
UNESCO conference: Memory of the World in the Digital Age
26-28 September 2012, Vancouver, BC, Canada
Memory of the World in the Digital Age
SCAPE researchers Christoph Becker and Andreas Rauber of the Vienna University of Technology and Hannes Kulovits of the Austrian State Archives will be hosting a workshop on “Roles and responsibilities in digital preservation decision making: Towards effective governance”. Based on a Reference Model for Digital Preservation capabilities, this interactive session will illustrate typical roles and their responsibilities in two areas: Preservation Planning and Preservation Operations. The purpose of the session is to show the state of the art in digital preservation decisions and support prospective adopters of systematic preservation planning in analysing their readiness for transparent governance processes. The full preliminary programme is available here.
iPres 2012 conference
1-5 October 2012, Toronto, Canada
https://ipres.ischool.utoronto.ac/
The largest event in the area of digital preservation is of course the iPres2012 conference. SCAPE will participate with several papers and a full-day workshop on ‘Open research challenges in digital preservation’. The goal of this interactive workshop is to elicit and discuss DP research challenges to be tackled in the next decade. It brings together researchers in order to step beyond the limitations of solutions that are applicable now, and develop concepts, models and solutions for upcoming challenges. This will cover diverse areas such as Information Systems, Databases, Information Retrieval, Library and Archival Science, Content Management, Modeling, Simulation, Human-Computer Interaction, Scholarly Communication, Systems Engineering, Cloud computing, Security and others. More information is available here.
