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 |
