Hai everybody,
I am trying to register two color images(one is the
reference and the other is the rotated as well as
shifted and scaled) using Log polar transform.Here is
the algorithm:

I first converted the color to gray scale image
Then applied fourier transform to both images
Took the magnitude and applied log polar transform
Used cross correlation to match images
When i checked for the correlation i am getting the
peaks(after inverse fourier transform) but i am not
getting the (log r,theta) coordinates properly,that is
i am getting the same values for all kinds of
rotations.....
Please tell me whether i am moving in the right
direction and also tell me what should be done to
calculate the rotation as well as shift... I would be grateful to
you if you could help me in
this matter....I am trying out this in Matlab....It's kinda urgent
ppl....

Thanking you and waiting for your reply eagerly,
Karthik
