Using handwritten characters we address two questions (i) what is the group identification performance of different alphabets (upper and lower case) and (ii) what are the best characters for the verification task (same writer/different writer discrimination) knowing demographic information about the writer such as age,sex or country of birth. The Bhattacharya distance is used to rank different ...

Writer identification and verification has been studied over the past decade due to the high demand of such implementations in a wide variety of offline handwritten data applications. Among the applications are verification of the identity of a person whom he or she claimed to be and forensic and historic document analysis in identifying the identity of the writer of the documents. This paper p...

Writer identification (writer-id), an important field in biometrics, aims to identify a writer by their handwriting. Identification existing writer-id studies requires complete document or text, limiting the scalability and flexibility of realistic applications. To make application more practical (e.g., on mobile devices), we focus novel problem, letter-level online writer-id, which only few tr...

In this paper a novel method for writer identification and retrieval is presented. Writer identification is the process of finding the author of a specific document by comparing it to documents in a database where writers are known, whereas retrieval is the task of finding similar handwritings or all documents of a specific writer. The method presented is using Convolutional Neural Networks (CN...

This paper introduces a novel method for online writer identification. Traditional methods make use of the distribution of directions in handwritten traces. The novelty of this paper comes from 1)We propose a text-independent writer identification that uses handwriting stroke’s probability distribution function (SPDF) as writer features; 2)We extract four dynamic features to characterize writer...

Stories and story-telling are a cultural achievement of significant relevance, even in modern times. Since ancient times stories have served to entertain and teach mankind to “transmit” knowledge from generation to generation. Story-telling ranges from simple aural narrations to traditional inter-generational discourse and, in modern times, workflow-oriented organizational learning. Web-based s...
