A survey of document image word spotting techniques
TL;DR: The nature of texts and inherent challenges addressed by word spotting methods are thoroughly examined and the use of retrieval enhancement techniques based on relevance feedback which improve the retrieved results are investigated.
Journal ArticleDOI
HMM word graph based keyword spotting in handwritten document images
TL;DR: The proposed approach achieves KWS results comparable to those obtained with the recently-introduced "BLSTM neural networks KWS" approach and clearly outperform the popular, state-of-the-art "Filler HMM" KWS method.

Script Identification of Multi-Script Documents: A Survey
TL;DR: The most vital processes in script identification are addressed in detail: identification and discriminating methods, features extraction (local and global, and classification), and classification.
Journal ArticleDOI
A Survey on handwritten documents word spotting
TL;DR: This paper gives an overview of published research efforts in the area of handwritten document image word spotting and on the technologies used in the field and describes a general model for document word spotting.

Cross-language framework for word recognition and spotting of Indic scripts
TL;DR: In this article, a cross-language platform for handwritten word recognition and spotting for such low-resource scripts where training is performed with a sufficiently large dataset of an available script and testing is done on other scripts (considered as target script).

A tutorial on hidden Markov models and selected applications in speech recognition
TL;DR: In this paper, the authors provide an overview of the basic theory of hidden Markov models (HMMs) as originated by L.E. Baum and T. Petrie (1966) and give practical details on methods of implementation of the theory along with a description of selected applications of HMMs to distinct problems in speech recognition.

Online and off-line handwriting recognition: a comprehensive survey
TL;DR: The nature of handwritten language, how it is transduced into electronic data, and the basic concepts behind written language recognition algorithms are described.

The IAM-database: an English sentence database for offline handwriting recognition
Urs-Viktor Marti,Horst Bunke +1 more
TL;DR: A database that consists of handwritten English sentences based on the Lancaster-Oslo/Bergen corpus, which is expected that the database would be particularly useful for recognition tasks where linguistic knowledge beyond the lexicon level is used.

Using a statistical language model to improve the performance of an HMM-based cursive handwriting recognition systems
U.-V. Marti,Horst Bunke +1 more
TL;DR: A novel feature of the system is that the HMM is applied in such a way that the difficult problem of segmenting a line of text into individual words is avoided and linguistic knowledge beyond the lexicon level is incorporated in the recognition process.

Word spotting for historical documents
Toni M. Rath,R. Manmatha +1 more
TL;DR: It is shown in a subset of the George Washington collection that such a word spotting technique can outperform a Hidden Markov Model word-based recognition technique in terms of word error rates.
