Development of an Automated Technique for Reconstructing Jawi Characters in Historical Documents

The old documents in Jawi script are still being used widely for references. The quality of the hard copies of those scripts will be deteriorating as time passes. Manual reconstruction may take long time if the documents are sufficiently thick. The accuracy of the document image recognition algorith...
