IMPORTANCE OF POST PROCESSING FOR IMPROVED BINARIZATION OF TEXT DOCUMENTS
Harjinder Singh Dhanjal . · International Journal of Research in Engineering and Technology · 2013
Post processing uses mathematical morphologies to improve the quality of Binary image of a Document.It is observed that when a document is written using a ball point pen or when there is a problem in toner of printer then in scanned copy of such documents there are some minimal stroke gaps which are not easily visible to human eye.But a machine can easily recognise these gaps.These gaps lower the quality of binary image of a document.Post processing very important for improve the accuracy of binarization of degraded documents.In this paper a mathematical technique is discussed to improve the quality of binary image.
