Classical image segmentaion problem

hi I am trying to extract the fields in the image for example the whole field against first anme and so on. Now i have achieved partial results from vertical and horizontal edge detection but i want to explore any new algorithm or ideas hints etc. Attached is my image any suggestions are more than welcome guys.

This is an obvious case for a template . No edge detection needed. You have a form! Take advantage of that fact! Just have a master image that is perfectly aligned with the rows and columns of the image. Then determine the box coordinates for all the fields on that perfect master form. Now, for a "test" form, use imregister() to align it to the master one, then simply use the known coordinates of the fields to extract the sub-images. There are examples for aligning images in the help for imregister.
