How to align two images which are only several pixels away in vertical direction?
Also look at imregcorr. It uses phase correlation and is easier to use than imregister. I'd start there.

Image Resistration Code Optimization
Take a look at imregcorr. Do you have initial conditions for the expected transformation? If so, this will speed up imregister.

i want to know the pixel intensity value in an image but it gives different results using data cursor and command.which one is correct? and why it is showing differently?
Impixelinfo is reporting in x,y convention. You are indexing in row,col. Index A(y,x) and this should resolve the issue.
