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...

The Ghost Map

Widely viewed as the “father of contemporary epidemiology,” Dr. John Snow is among the most famous of public health fi gures (1). His “grand experiment” in 1854 (comparing cholera deaths in South London households that had consumed contaminated water with those that had not consumed contaminated water) is often considered a classic (2), but the Broad Street pump outbreak is perhaps the more fam...
