A writer identification and verification system
Pattern Recognition Letters, 2005In this paper, we show that both the writer identification and the writer verification tasks can be carried out using local features such as graphemes extracted from the segmentation of cursive handwriting. We thus enlarge the scope of the possible use of these two tasks which have been, up to now, mainly evaluated on script handwritings.

The ICDAR2011 Arabic Writer Identification Contest
2011 International Conference on Document Analysis and Recognition, 2011 Arabic writer identification is a very active research field. However, no standard benchmark is available for researchers in this field. The aim of this competition is to gather researchers and compare recent advances in Arabic writer identification.

Writer identification by writer's invariants
Proceedings Eighth International Workshop on Frontiers in Handwriting Recognition, 2003This communication deals with the problem of writer identification. If the assumption of writing individuality is true then graphical fragments that constitute it should be individual too. Therefore we propose a morphological grapheme based analysis to make writer identification. Template Matching is the core of the approach.

Methods for writer identification
Proceedings of Third International Conference on Electronics, Circuits, and Systems, 2002Relatively simple methods for writer identification are presented in this work. The problems related to image acquisition, image preprocessing, feature selection and extraction as well as clustering and identification are analyzed. A couple of features is proposed towards a better discrimination result.

Automatic Identification of Writers
1988Using handwriting as a means of input to a computer has several advantages, currently not appreciated sufficiently. The use of pen (and paper) gives the user the opportunity of providing the computer with textual and graphic information in a “natural” fashion and it is expected that the keyboard will continue to be an obstacle for large-scale human ...

Automatic writer identification
, 2014 Στόχος αυτής της διπλωματικής είναι η ανάπτυξη συστήματος, το οποίο θα είναι υπεύθυνο για την ταυτοποίηση γραφέα, απο χειρόγραφα κείμενα του. Το σύστημα θα είναι σε θέση να επαληθεύει την ταυτότητα του συγγραφέα ενός χειρόγραφου κειμένου, συγκρίνοντας διάφορα χαρακτηριστικά γραφής του.

Writer Identification in Handwritten Documents
Ninth International Conference on Document Analysis and Recognition (ICDAR 2007), 2007This work presents an effective method for writer identification in handwritten documents. We have developed a local approach, based on the extraction of characteristics that are specific to a writer. To exploit the existence of redundant patterns within a handwriting, the writing is divided into a large number of small sub-images, and the sub-images ...

Writer Retrieval and Writer Identification Using Local Features
2012 10th IAPR International Workshop on Document Analysis Systems, 2012Writer identification determines the writer of one document among a number of known writers where at least one sample is known. Writer retrieval searches all documents of one particular writer by creating a ranking of the similarity of the handwriting in a dataset.

Knowledge Transfer for Writer Identification
2018The technical literature on writer identification usually considers the best case scenario in terms of data availability, i.e., a database composed of hundreds of writers with several documents per writer is available to train the machine learning models. However, in real-life problems such a database may not be available.

Writer Identification for Handwritten Words
2017In this work we present a framework for recognizing writer for a handwritten word. We make use of allographic features at sub-word level. Our work is motivated by previous techniques which make use of a codebook. However, instead of encoding the features using the codewords, we exploit the discriminative properties of features that belong to the same ...
