You can use regionprops to get the Orientation. See my Image Segmentation Tutorial in my File Exchange : http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 for a demo on how to use regionprops.

Or see this page: http://homepages.inf.ed.ac.uk/rbf/CVonline/LOCAL_COPIES/OWENS/LECT2/node3.html

Or check the literature for how others have successfully done it: VisionBib OCR
