Hello Sajeesh,

As a Junior Electrical Engineering Student, I warn you that i will not be giving the most decent answer you are seeking, but I know a way to solve your problem.

In order to find the local displacement, you have to follow several alghorithms such as SURF, MSAC etc. There is already this method explained on the mathworks/help, on the following link.

I hope this helps,

Cheers!
