Transcoding of Document Images for Mobile Devices

In this paper we have presented a scheme for transcoding document images for presentation on handheld devices like PDA’s, e-books etc. We have proposed technqiues suitable, in particular,for images of documents of Indian languages having Devanagari based scripts (viz. Hindi, Marathi, Bengali, Assamese, etc). Appropriate compression scheme for textual component of document images exploiting script specific characteristics has been suggested. We have also explored use of the knowledge of the document model represented through standard ontology language for generation of document summary. An experimented system has been developed for validation of these schemes. 1
