How to do horizontal and vertical splitting in an image..?

I am working on features extraction for signature verification. Currently,I have done several processes until finding the gravity center point for that signature. What I need to do now is split the signature image into horizontal and vertical splitting consecutively as shown here http://postimg.org/image/o0uawhech/.
- Split the signature image with horizontal line passing through its geometric center to get top and bottom part of signature.
- Then, find geometric center for top and bottom part.
- Divide the top part with vertical line passing through its geometric center to get left and right part.
- Find the geometric centers for left and right parts of top part correspondingly.
p/s: Similarly, the bottom part is split using same method to obtain ten feature points.

Have you looked at how others have done it here: http://iris.usc.edu/Vision-Notes/bibliography/contentschar.html#OCR,%20Document%20Analysis%20and%20Character%20Recognition%20Systems
Finding the center on a binary image is no problem:
[rows, columns] = find(binaryImage);
meanX = mean(columns);
meanY = mean(rows);
