How to separate horizontly on the basis of gaps or space

Hello friends,

I am trying to separate all characters vertically separated through gaps/spaces as highlighted in image through red, blue and green color

If I am trying to use bwlabel, it is separating connected components. thus I am losing ligatures and dots. Any help by providing me the link or sample code shall be highly appreciated.

Regards

Hi!

Do you need this for single or multi-line text?

For this simple case, I'd just get profiles. I would sum the image horizontally and vertically and look for spikes.

horizontalProfile = sum(grayImage, 1); % Sum across all rows.
verticalProfile = sum(grayImage, 2); % Sum across all columns.

But for more sophisticated algorithms, you'll need to check the OCR literature: http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems
