Optical character recognition (OCR) is a very popular research area since 1950's. Many people has done a lot of work on various scripts. Line segmentation is a very important step in OCR as the accuracy of the recognition algorithm highly depends on the correct line segmentation. Incorrect line segmentation not only decreases the accuracy but also may lead to some other errors. The objective of...

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

Given a set of handwritten documents, a common goal is to search for a relevant subset. Attempting to find a query word or image in such a set of documents is called word spotting. Spotting handwritten words in documents written in the Latin alphabet, and more recently in Arabic, has received considerable attention. One issue is generating candidate word regions on a page. Attempting to definit...

In this paper we propose new methods for ordering the Web pages returned from search engines. Given a few search keywords, nowadays most search engines could retrieve more than a few thousand Web pages. The problem is how to order the retrieved Web pages and then to present the most relevant Web pages first. We propose new factors to allow relevant Web pages to be ranked higher. The factors inc...

ÐWhile numerous page segmentation algorithms have been proposed in the literature, there is lack of comparative evaluationÐempirical or theoreticalÐof these algorithms. In the existing performance evaluation methods, two crucial components are usually missing: 1) automatic training of algorithms with free parameters and 2) statistical and error analysis of experimental results. In this paper, w...

As day by day new computer technologies are emerging in the area of image processing, especially in the field of segmentation. Image Segmentation is a hotspot and important process of image processing. Several algorithms and techniques are developed for image segmentation. It is a technique of partitioning digital image into multiple regions called segments for further analysis. It is very usef...

In this paper, we explore the use of new page segmentation algorithm using both visual and structural mark-up (,) to partition web pages into blocks and investigate how to take advantage of block-level evidence to improve retrieval performance in the web. We propose a new ranking function that combines content and link rank based on propagation of scores over links on block-to-page grap...
