JAYASHREE SUBRAHMONIA IBM T.J. Watson Research, P.O. Box 218 / Route 134, Yorktown Heights, NY 10598, U. S. A. E-mail: [email protected] This paper addresses the problem of improving the performance of an online, writer-independent, large-vocabulary, unconstrained, handwriting recognition system by clustering writers with similar writing styles. Recognition performance is enhanced by identify...

We propose an HMM-based text-indicated writer verification method, which is based on a challenge and response type of authentication process. In this method, a different text including ordinary characters is used on every occasion of verification. This text can be selected automatically by the verification system so as to reflect a specific writer's personal features. The specific writer is acc...

Relativistic Programming is a technique that allows low overhead, linearly-scalable concurrent reads. It also allows joint access parallelism between readers and a writer. Unfortunately, it has so far been limited to a single writer so it does not scale on the write side. Software Transactional Memory (STM) is a technique that allows programs to take advantage of disjoint access parallelism on ...

This paper is about retrieving the closest matches from a set of scanned handwritten documents based on a query that is a document image. System indexing and retrieval is based on writer characteristics, textual content as well as document meta data such as writer profile. Documents are indexed using global image features, e.g., stroke width, slant, word gaps, as well local features that descri...
