In this paper, we apply an Information Retrieval model for the writer identification task. A set of local features is defined by clustering the graphemes produced by a segmentation procedure. Then a textual based Information Retrieval model is applied. After a first indexation step, this model no longuer requires image access to the database for responding to a specific query, thus making the p...

In this paper, we describe a new method to identify the writer of handwritten documents. There are many methods for signature verification or writer identification, but most of them require segmentation or connected component analysis. They are the kinds of content dependent identification methods as signature verification requires the writer to write the same text (e.g. his name). In our new m...

In December 1868 we pointed out that in these days of report writing, when the existence of sundry departments absolutely depends on the labors of the medical executive, the amount of clerical work imposed on Civil Surgeons was getting formidable, and that by an official quibble they were supposed to have no office, and therefore no clerk or office allowance. Civil Surgeons were, therefore, com...

The semantics of reader-writer locks allow read-side concurrency. Unfortunately, the locking primitives serialize access to the lock variable to an extent that little or no concurrency is realized in practice for small critical sections. Relativistic programming is a methodology that also allows readside concurrency. Relativistic programming uses different ordering constraints than reader-write...

Reader-writer synchronization relaxes the constraints of mutual exclusion to permit more than one process to inspect a shared object concurrently, as long as none of them changes its value. On uniprocessors, mutual exclusion and readerwriter locks are typically designed to de-schedule blocked processes; however, on shared-memory multiprocessors it is often advantageous to have processes busy wa...

In this paper we present a survey of the literature on Arabic writer identification scheme and up-to date techniques employed in identification. The paper begins with an overview of the various writer identification schemes in Arabic and Persian languages. After that, an attempt is made to describe the complex character of Arabic strokes. Previous studies have used a number of Arabic datasets c...
