hello friends, to perform skew detection and correction, iam using horizontal projection profile. so i need the code for horizontal projection profile to segment lines and i need the code for horizontal projection profile of each word, for image containing handwritten characters.

First pick an algorithm from section 23 of the Vision Bibliography: http://iris.usc.edu/Vision-Notes/bibliography/contents.html. Then come back here with your MATLAB coding questions.

But what if, in handwriting, descenders in one row dip below some risers in the row below? Those two rows would not be detected as two rows with any(). And with sum() and mean(), the descenders would get clipped. So to be really robust, you'd need something more sophisticated than these simple functions. But I can't spend the time to develop a robust OCR program for anyone.

You need the ascenders and descenders for proper classification of the characters. Horizontal projection is simply not sufficient for the case where you do not have clean separation between the lines.
