i'm trying to enhanced image by gaussian high pass filter but it can't work... can you help me to repair my program? thangkyou before

% function GaussianHighPass

[m n]=size(image.jpg);

f_transform=fft2(image.jpg);

f_shift=fftshift(f_transform);

x0=m/2;

y0=n/2;

D0=70;

a=12.53;

b=-4;

for x=1:m;

    for y=1:n;

        D=sqrt((x-x0)^2+(y-y0)^2);

        hpf(x,y)=a*(1-exp(-(D^2)/(2*(D0^2))))+b;  

    end

end

filter_apply=conv2(image.jpg,hpf,'same');

figure,imshow(filter_apply)

image_orignal=ifftshift(filter_apply);

image_filter_apply=abs(ifft2(image_orignal));

figure,imshow(image_filter_apply,[])
