Writer Identification and Verification from Intra-variable Individual Handwriting
The handwriting of an individual may vary excessively with many factors such as mood, time, space, writing speed, writing medium, utensils etc. Therefore, it becomes more challenging to perform automated writer verification/ identification on a particular set of handwritten patterns (e.g. speedy handwriting) of a person, especially when the system is trained using a different set of writing pat...
متن کاملUsing Perturbed Handwriting to Support Writer ID in the Presence of Severe Data Constraints
Usually we assume large amount of data for writer identification, what if only little data is available, e.g., 1 page, 1 paragraph, or even 1 line? Several reasonable assumptions in forensics: • The writers are no longer available. • The writers might not be collaborative. The question is then: what can we do in this situation? • Use of synthetic data has been studies in fields like: signature ...
متن کاملBiometric Personal Identification Based on Handwriting
In this paper, we describe a new method to identify the writer of Chinese handwriting 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 o...
متن کاملWriter Identification from Non-uniformly Skewed Handwriting Images
Many techniques have been reported for handwriting-based writer identification. Most such techniques assume that the written text is fixed (e.g., in signature verification). In this paper we attempt to eliminate this assumption by presenting a novel algorithm for automatic text-independent writer identification from non-uniformly skewed handwriting images. Given that the handwriting of differen...
متن کاملA Proposal for a Text-Indicated Writer Verification Method - Document Analysis and Recognition, 1997., Proceedings of the Fourth International Conference on
W e propose an on-line writer verification method to improve the reliability of verifying a specific system user. In the proposed method, a different text including ordina y characters is used on eve y verification process. This text can be selected automatically by the verification system so as to reflect the specific writer's fentures. A specific writer is accepted only when the same text, wh...
متن کاملMapping Transcripts to Handwritten Text
In the analysis and recognition of handwriting, a useful first task is to assign ground truth for words in the writing. Such an assignment is useful for various subsequent machine learning tasks for performing automatic recognition, writer verification, etc. Since automatic word segmentation and recognition can be error prone, an intermediate approach is to use a text file that is a transcripti...
