Feature Mixing for Writer Retrieval and Identification on Papyri Fragments [PDF]

open access: yesProceedings of the 7th International Workshop on Historical Document Imaging and Processing, 2023
This paper proposes a deep-learning-based approach to writer retrieval and identification for papyri, with a focus on identifying fragments associated with a specific writer and those corresponding to the same image. We present a novel neural network architecture that combines a residual backbone with a feature mixing stage to improve retrieval ...

Evaluating learned feature aggregators for writer retrieval [PDF]

open access: yesInternational Journal on Document Analysis and Recognition (IJDAR)
AbstractTransformers have emerged as the leading methods in natural language processing, computer vision, and multi-modal applications due to their ability to capture complex relationships and dependencies in data. In this study, we explore the potential of transformers as feature aggregators in the context of patch-based writer retrieval, with the ...

Novel methods for writer identification and retrieval [PDF]

open access: yes, 2015
Writer identification is the task of identifying the writer of a handwritten document, based on a set of documents where the authors are known. It can be used e.g. for tasks in forensics and for historical document analysis. In contrast to this, writer retrieval is to receive a ranking of the pages in the set of documents sorted according to the ...

Writer Retrieval for Historical Documents [PDF]

open access: yes
This thesis focuses on writer retrieval, a task that ranks documents of interest based on their similarity to a given handwritten query sample. The primary objective is to identify documents authored by the same writer, with the similarity determined through feature extraction and application of a distance or similarity metric. Manual identification of

Self-supervised Vision Transformers for Writer Retrieval [PDF]

open access: yes
While methods based on Vision Transformers (ViT) have achieved state-of-the-art performance in many domains, they have not yet been applied successfully in the domain of writer retrieval. The field is dominated by methods using handcrafted features or features extracted from Convolutional Neural Networks.

Writer Retrieval using Compact Convolutional Transformers and NetMVLAD

open access: yes2022 26th International Conference on Pattern Recognition (ICPR), 2022
This paper presents a method for writer retrieval where embeddings of patches extracted at SIFT keypoint locations are learned by a Compact Convolutional Transformer (CCT), a modified attention-based transformer architecture including convolutions ...

Writer identification through information retrieval: the allograph weight vector [PDF]

open access: yes, 2008
We show a number of promising results in writer identification, by recasting the traditional information retrieval (IR) problem of finding documents based on the frequency of occurrence of their terms. In IR, the tf-idf is a well-known statistical measure that weighs the importance of certain terms occurring in a database of documents.

Using content based image retrieval techniques for the indexing and retrieval of Thai handwritten documents [PDF]

open access: yes, 2010
This paper proposes the use of content base image retrieval (CBIR) techniques for indexing and retrieval of handwritten documents in Thai language. Issues associated with Thai handwritten documents are the lack of spacing between words, multi-level ...

The temporal structure between retrieval and anticipation in the novel "The Scorpion" by Hossein Mortezaian Abkanar

open access: yesآداب الكوفة, 2017
This study, according to the descriptive-analytical method, aims to study the temporal structure in the novel The Scorpion. The study began with a detailed discussion of the critics' perceptions of the topic of time and the techniques of its formation ...
