Improving Information Retrieval in Multiwriter Scenario by Exploiting the Similarity Graph of Document Terms

Pau Riba, Anjan Dutta, Sounak Dey, Josep Llados, Alicia Fornes
2017 2017 14th IAPR International Conference on Document Analysis and Recognition (ICDAR)  
In document analysis, information retrieval receives a lot of attention in terms of symbol and word spotting.  ...  In this paper, we explore different analytics of graphs constructed from words or graphical symbols, such as diffusion, shortest path, etc. to improve the performance of information retrieval methods in  ...  ACKNOWLEDGMENTS This work has been partially supported by the European Union's research and innovation program under the Marie Skłodowska-Curie grant agreement No. 665919, the Spanish project TIN2015-70924  ...

Segmentation-free word spotting with exemplar SVMs

Jon Almazán, Albert Gordo, Alicia Fornés, Ernest Valveny
2014 Pattern Recognition  
Rothacker et al. [14] exploits the use of the BoW representation to feed a HMM and avoids the segmentation step by means of a patch-based framework.  ...  Documents are represented with a grid of HOG descriptors, and a sliding-window approach is used to locate the document regions that are most similar to the query.  ...  This variability is usually much higher in a multiwriter scenario.  ...

Y. Liang, M. C. Fairhurst, R. M. Guest, M. Erbilek
2016 International journal of pattern recognition and artificial intelligence  
Finally, we introduce tools to support visualisation of the extracted features in a comparative way, showing how they can best be exploited in the implementation of a content-based image retrieval (CBIR  ...  in terms of the deployment of feature extraction techniques and handwriting metrics.  ...  They also thank Dr Catherine Richardson for information provided on the documents comprising the MEMDB database.  ...

Keyword spotting in handwritten document images using supervised and unsupervised representations [article]

Άγγελος Γιώτης, University Of Ioannina
Vast collections of documents available in image format need to be efficiently digitized for information retrieval purposes.  ...  Many approaches from the document analysis and recognition research community have been proposed to alleviate the search process.  ...  ACKNOWLEDGEMENTS With the completion of this thesis, a large chapter of my life is coming to a close.  ...
