Writer verification using texture-based features

International Journal on Document Analysis and Recognition (IJDAR), 2011
In this work, we propose a writer verification system that takes into account texture-based features and dissimilarity representation. Textures of the handwritings are created based on the inherent properties of the writer. Independent of the writing style, the proposed method reduces the spaces between lines, words, and characters, producing a texture

Online Writer Verification Using Kanji Handwriting

2006
This paper investigates writer verification using handwritten kanji characters on a digitizing tablet. Features representing individuality, which are derived from the knowledge of document examiners, are automatically extracted and then the features effective in writer verification are selected from the extracted features.

Automatic handwriting analysis for writer identification and verification

Proceedings of the 7th International Conference on Software Engineering and New Technologies, 2018
The work presented in this paper in the field of automatic analysis of handwritten documents for the recognition of individuals through their handwriting. We proposed a hybrid method (local and global) for writer recognition. The proposed method is based on the detection and localization of the points in the image of the Harris editor and the global ...

HOG and LBP Based Writer Verification

2020
We propose a writer-specific off-line writer verification procedure to improve the reliability of the verification system. It has to be a challenging task, particularly in the off-line scenario, which uses images of the scanned document, where the dynamic information is not available.

Relevance of Grapheme’s Shape Complexity in Writer Verification Task

2020 IEEE 21st International Conference on Information Reuse and Integration for Data Science (IRI), 2020
Recognizing and identifying people, based on their physical and behavioral characteristics, have always had a wide range of applications, inciting researchers to propose dedicated human recognition systems for each human characteristic. These systems operate according to two different modes: identification mode, where the task is to assign one of the ...

Writer Verification in Forensic Handwriting Examination: A Pilot Study

2016 15th International Conference on Frontiers in Handwriting Recognition (ICFHR), 2016
Writer verification in forensic handwriting examination is usually performed on just a few lines of text available in both genuine and questioned documents. In such a case, the only source of information being the feature values measured on the document at hand, the large majority of the methods proposed in the realm of pattern recognition cannot be ...

Arabic writer verification based on shape complexity

2019 7th International Workshop on Biometrics and Forensics (IWBF), 2019
Writer recognition task has received a lot of interests during the last decade due to it wide range of applications. This task includes writer identification and/or verification. In this paper we propose an original approach for the Arabic writer verification based on shape complexity. In this approach two handwritten words are submitted to the system,

Using HMM Based Recognizers for Writer Identification and Verification

Ninth International Workshop on Frontiers in Handwriting Recognition, 2004
In this paper, we use HMM based recognizers for the identification and verification of persons based on their handwriting. For each writer, we build an individual recognizer and train it on text lines of that writer. This gives us recognizers that are experts on the handwriting of exactly one writer.

Transparency Techniques for Neural Networks trained on Writer Identification and Writer Verification

2023
Neural Networks are the state of the art for many tasks in the computer vision domain [SBM+17, ZTLT21]. This also includes the areas of Writer Identification and Writer Verification, where the goal is to identify the author of a handwritten text. A more novel task is the interpretability of neural networks, which are considered ”black box” systems, and
