Transform the high passed 2-D FFT phase to Log Polar space

I want to transform the high passed 2-D FFT phase to Log Polar space, can anyone help me with the matlab code for this

FA = fftshift(fft2(I));

w=0.5; % frequency normalized

N=2; %filter order

b=butter(N,w,'high');

A=ftrans2(b);

IA=imresize(A,[512 512]);

highPass=IA.*abs(FA);% high passed shifted fft2 of image I

Your filter creation is badly broken, so transforming it to Log Polar is not going to produce meaningful results.

For more on your filter creation, see your previous question, http://www.mathworks.com/matlabcentral/answers/28591-high-pass-filter
