Question

I am doing my major project as part of my MCA course. It's an appliction for detecting humps and potholes. A similar paper has already been accepted by IEEE. I read those papers but can't understand it.
What I have is an accelarometer and I can measure the acceleration in 3 directions(x,y,z) and 3 rotation angles (azimuth, pitch,role).
How can I detect a pothole or himp by placing this on a car. I only need the logic to calculate it using those values.
Thanks.
