Improving Writer Identification Through Writer Selection

In this work we present a method for selecting instances for a writer identification system underpinned on the dissimilarity representation and a holistic representation based on texture. The proposed method is based on a genetic algorithm that surpasses the limitations imposed by large training sets by selecting writers instead of instances. To show the efficiency of the proposed method, we ha...

Hybrid writer-independent-writer-dependent offline signature verification system

Standard signature verification (SV) systems are writer-dependent (WD), where a specific classifier is designed for each individual. It is inconvenient to ask a user to provide enough number of signature samples to design his WD classifier. In practice, very few samples are collected and inaccurate classifiers maybe produced. To overcome this, writer-independent (WI) systems are introduced. A g...

An essay on Jewish ethnography as a ‘Jew-ish’ ethnographer

this article offers a reflexive and anthropological contribution to the current volume of scripta Instituti Donneriani aboensis. It reflects on the experience of conducting anthropologic al work at home – or across homes – I considered this research to be an experience of ‘Jewish ethnog raphy’ as a Jewish ethnographer. However, my own ‘Jew-ish’ background meant that I had become ‘neither fish n...

Discriminative Writer Adaptation

We propose a general method for adapting a writerindependent classifier to an individual writer. We employ a mixture of experts formulation, where the classifiers are trained on weighted clusters of writers. The clusters are determined by which experts classify individual writing correctly. The method adapts by choosing the appropriate combination of classifiers for a new user. It applies to an...
