A novel variational model for noise robust document image binarization
Neurocomputing, 2019Binarization is a fundamental problem in document image analysis systems. Different from current thresholding techniques, a novel variational model is proposed for noise robust document image binarization in this work, which is inspired by two classical ...

LayoutParser: A Unified Toolkit for Deep Learning Based Document Image Analysis
IEEE International Conference on Document Analysis and Recognition, 2021Recent advances in document image analysis (DIA) have been primarily driven by the application of neural networks. Ideally, research outcomes could be easily deployed in production and extended for further investigation.

Granulometric analysis of document images
Object recognition supported by user interaction for service robots, 2003We report on new form of multivariate granulometries based on rectangles of varying size and aspect ratio. These granulometries are used for describing visual similarity between document images. Rectangular granulometries are used to probe the layout structure of document images, and the rectangular size distributions derived from them are used as ...

Analysis of synthetic document images
Proceedings of the Fifth International Conference on Document Analysis and Recognition. ICDAR '99 (Cat. No.PR00318), 1999Interoperability and reusability are becoming challenging problems in document engineering that cannot be solved satisfactorily with converters and filters. This paper advocates a new approach for logical structure recovery by means of document recognition techniques that operate on synthetic images, such as those rendered by a PostScript interpreter ...

Script Identification of Document Image Analysis
First International Conference on Innovative Computing, Information and Control - Volume I (ICICIC'06), 2006Script identification prior to OCR is necessary in document image analysis. And each script has unique spatial distribution and visual attribute that make it possible to identify itself from other languages. The key technology of script identification algorithm is to abstract effective measure feature.

Chart analysis and recognition in document images
Proceedings of Sixth International Conference on Document Analysis and Recognition, 2002Hidden Markov models are a probabilistic modeling tool for time series data. It has been successfully applied to many areas, such as speech recognition, hand-written character recognition, etc. In this paper, we present a novel statistical approach using ergodic hidden Markov models to recognize scientific charts.

Image based typographic analysis of documents
Proceedings of 2nd International Conference on Document Analysis and Recognition (ICDAR '93), 2002An approach to image based typographic analysis of documents is provided. The problem requires a spatial understanding of the document layout as well as knowledge of the proper syntax. The system performs a page synthesis from the stream of formatting commands defined in a DVI file.
