Devanagari script is a two dimensional composition of symbols. It is highly cumbersome to treat each composite character as a separate atomic symbol because such combinations are very large in number. This paper presents a two pass algorithm for the segmentation and decomposition of Devanagari composite characters/symbols into their constituent symbols. The(More)
A patent always contains some images along with the text. Many text based systems have been developed to search the patent database. In this paper, we describe PATSEEK that is an image based search system for US patent database. The objective is to let the user check the similarity of his query image with the images that exist in US patents. The user can(More)
This paper presents an algorithm for seg-mentation of touching Devanagari characters (also referred to as conjuncts) into its constituent symbols and characters. Proposed algorithm extensively uses structural properties of the script. Statistical information about the height and width of character boxes, which are vertically separate from their neighbours ,(More)
The visual photopigments of simple deuter-anomalous trichromats inferred from color matching, " Vis. Abstract—The reading process has been widely studied and there is a general agreement among researchers that knowledge in different forms and at different levels plays a vital role. This is the underlying philosophy of the Devanagari document recognition(More)
This paper describes a method for correction of optically read Devanagari character strings using a Hindi word dictionary. The word dictionary is partitioned in order to reduce the search space besides preventing forced match to an incorrect word. The dictionary partitioning strategy takes into account the underlying OCR process. The dictionary words at the(More)
Information Technology Outsourcing (ITO) has generated considerable research interest since the historic Eastman Kodak deals of 1989. In this paper, a model has been developed for making the ITO decision based on the Analytic Hierarchy Process (AHP). Two hierarchies have been developed-one for making a choice of activities to outsource and another to choose(More)
Optical character reading has been a topic of research for several decades. However, human competing performance is still a distant reality. One of the primary reasons of human beings' superior performance is our ability to invoke varying knowledge stores which are relevant to the given situation and integrate them to arrive at meaningful and consistent(More)
