HDL Code Generation for Phase Correlation

I have the matlab codes for phase correlation given two images. And I would like to convert this code to VHDL codes but i have very little knowledge on VHDL. Can anyone assist? Thank you.

image1 = rgb2gray(imread('image1.jpg'));

image2 = rgb2gray(imread('image2.jpg')); F1 = fft2(image1);

F2 = fft2(image2);

conj_F2 = conj(F2); % complex conjugate of F2

FFTR = F1.*conj_F2;

magFFTR = abs(FFTR);

FFTRN = (FFTR./magFFTR); % calculate cross-power spectrum

result = ifft2(double(FFTRN));
