Locating text in color documents

C. Strouthopoulos, N. Papamarkos, A. Atsalakis, C. Chamzas
Proceedings 2001 International Conference on Image Processing (Cat. No.01CH37205)  
In complex color documents, text, drawings and graphics are appeared with millions of different colors. In many cases, text regions are overlaid onto drawings or graphics.  ...  In this paper, a new method is proposed to automatically detect and extract text in mixed type color documents.  ...  OPTIMAL COLOR REDUCTION In complex color documents, text and graphics may be distributed in millions of colors. This introduces difficulties when text extraction and recognition is needed.  ...

Interactive TreemapsWith Detail on Demand to Support Information Search in Documents [article]

Stefan Schlechtweg, Petra Schulze-Wollgast, Heidrun Schumann
2004 EUROVIS 2005: Eurographics / IEEE VGTC Symposium on Visualization  
This paper addresses the issue of how information visualization techniques can be used to assist full-text search in electronic documents.  ...  We use a treemap to visualize the basic structure of the document and exploit color coding to show the distribution of query terms on various levels of the hierarchy.  ...  From the treemap he or she can then directly jump to the desired location in the text (cf. Figure 9 ). Conclusion In this paper we have addressed the problem of full-text search in documents.  ...

Text Region Extraction in a Document Image Based on Discrete Wavelet transforms

S. Audithan, RM. Chandrasekaran
2010 International Journal of MC Square Scientific Research  
This paper presents a new approach for extracting text region from the document images employing the discrete wavelet transform.  ...  The detection of text region is achieved by the discrete wavelet transforms. Experimental results show that the proposed method gives better text extraction from the document images.  ...  It defines edges as locations in an image where there is a sudden variation in the grey level or color of pixels.  ...

Automatic Extraction of Data from Bar Charts

Rabah A. Al-Zaidy, C. Lee Giles
2015 Proceedings of the Knowledge Capture Conference on ZZZ - K-CAP 2015  
We evaluate the eectiveness of our method on bar charts drawn from the web as well as charts embedded in digital documents.  ...  The extraction process is fully automated using image processing and text recognition techniques combined with various heuristics derived from the graphical properties of bar charts.  ...  The first step is to automatically locate text regions in the image. The next step is to apply OCR recognition to these text components.  ...
