We have collected, ground-truthed and organised a number of datasets which are available for research and/or personal use.
The dataset, part of the IMPACT Centre of Competence in Digitisation (digitisation.eu), contains more than half a million representative text-based images compiled by a number of major European libraries. Covering texts from as early as 1500, and containing material from newspapers, books, pamphlets and typewritten notes, the dataset is an invaluable resource for future research into imaging technology, OCR and language enrichment.
This dataset has been created primarily for the evaluation of layout analysis (physical and logical) methods. It contains realistic documents with a wide variety of layouts, reflecting the various challenges in layout analysis. Particular emphasis is placed on magazines and technical/scientific publications which are likely to be the focus of digitisation efforts. Each image in the dataset has associated comprehensive and detailed ground truth enabling in-depth evaluation.
This dataset contains contains scans of index cards from the UK's Natural History Museum lepidoptera index. The text is typewritten with handwritten annotations.
This online repository is the main point of reference for all activities related to evaluation within the scope of the Europeana Newspapers project. Its main goal is to provide a representative collection of all the types of newspapers which are and/or might be subject of ongoing or future digitisation activities. As such, it is hosting scanned images, metadata and ground truth (a representation of the ideal result of a processing step like OCR or layout analysis) on the level of individual newspaper pages.
The purpose of these images is to serve as examples of conditions to be addressed in the TR and EE subprojects. These conditions relate to image artefacts (inherent in the document as well as introduced during image capture), layout and fonts/language.
This is the example and evaluation dataset used for the ICDAR2015 Competition on Recognition of Documents with Complex Layouts, as it was made available to the participants of the competition.
This is the example and evaluation dataset used for the ICDAR2013 Competition on Historical Newspaper Layout Analysis, as it was made available to the participants of the competition.
This is the example and evaluation dataset used for the ICDAR2013 Competition on Historical Book Recognition, as it was made available to the participants of the competition.
This is the example and evaluation dataset used for the ICDAR2011 Historical Document Layout Analysis Competition, as it was made available to the participants of the competition.
