Using typography in document image analysis
, 1998 Even if font usage plays an important role in Document Image Analysis (DIA), recognition systems generally take the concept of font management in a weaker sense than in the production cycle. With the point of view of the document recognition community, we show how typographic information (characters bitmap, metrics, etc.) can improve existing analysis ...

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 ...

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.
