Many historical newspapers are being digitized. We aim to support access to them via text analysis of the OCRd content. However, the OCR includes many errors; so extracting meaningful content from it is difficult. A pipeline of processing steps is proposed. Here, we describe the first two steps: segmentation and genre identification. The segmentation procedure based on headings was quite succes...

We propose a mathematical knowledge browser which helps people to read mathematical documents. By the browser printed mathematical documents can be scanned and recognized by OCR (Optical Character Recognition). Then the meta-information (e.g. title, author) and the logical structure (e.g. section, theorem) of the documents are automatically extracted. The purpose of this paper is to show the ex...

The importance of effectively retrieving OCR text has grown significantly in recent years. We provide a brief overview of work done to improve the effectiveness of retrieval of OCR text.

A technique is presented that uses visual relationships between word images in a document to improve the recognition of the text it contains. This technique takes advantage of the visual relationships between word images that are usually lost in most conventional optical character recognition (OCR) techniques. The visual relations are defined to be the equivalence that exists between images of ...

The aim of the present work is to recognise printed Tamil text. Though commercial Optical Character Recognition (OCR) packages are available in the market for Roman Script, not much work has been done in the field of OCR for Indian languages. Indian scripts usually have a large number of symbols and hence, recognition is a challenging task. In the current context, a complete OCR in printed Tami...

This chapter is written entirely base on the conducted literature survey. This includes the approaches that have been conducted by other researchers. The literature survey for this project was conducted through two directions. A thorough study was done to capture the domain knowledge about the ancient Sri Lankan inscriptions. And on the other hand the technologies that were used for optical cha...

It is proposed a new code for contours of black-white plane images. This code was applied for optical character recognition of printed and handwritten characters. One can apply it to recognition of any visual
