Horizontal and Vertical Projection techniques for Line & word Segmentation Process in Offline Handwritten Gujarati Text

Abstract

This research paper describes two important techniques Horizontal & Vertical Projection for character segmentation process in Offline Handwritten Gujarati Text Recognition process (OHGTR). Segmentation is one of the key steps in Text Recognition process which is one of the factors in recognition accuracy. This research paper mainly focuses on segmentation techniques: Horizontal & Vertical projection. Recognition process is required to perform many pre-processing and post processing steps to recognize the character. If segmentation of scan documentation is properly happen then rest of the process will become easy otherwise it will reflect on final recognition process. It is easy to segment printed character scan document as compare to hand written document because of the same font size and style where in hand written text document is, the content character size is different, even the same document is written by the same person.

Keywords: OHGTR, Pre Processing, Post Processing, Horizontal & Vertical Projection, Offline Hand Written Text Recognition (OHGTR)
