hi,

I have two images which are rotated differently (images are same).

I want to align them in one direction (essentially reference free image alignment)...for which I am thinking of taking the help of covariance matrices.

I want computer to do this automatically...that is choosing the angle on his own with the help of eigenvectors of the covariance matrices of images.

My question is , is it possible if I decorrelate the vectors.?

can i find slope of a line if i know the principle eigenvector?

will decorrelating the vectors in a given region align them in one direction?
