Partitioning and searching dictionary for correction of optically read Devanagari character strings
2002
International Journal on Document Analysis and Recognition
Preserved Fulltext
This paper describes a method for correction of optically read Devanagari character strings using a Hindi word dictionary. ...
A tag is a string of fixed length associated with each partition. The correction process uses a distance matrix for assigning penalty for a mismatch. ...

A post-processor is an integral part of any OCR system. This paper proposes a method for detection and correction of errors in recognition results of handwritten and machine printed Gurmukhi OCR. ...
The corresponding code is then searched in the dictionary. If it exits then words from the list of the code are match with the source word. ...
The accuracy obtained for OCR result improvement was between 4.65% for machine printed words and names and 7.45% for names obtained from form processing. ...
