F = im2double(imread('cameraman.tif'));
I = rand(512);
I([1:size(F,1)] + 30, [1:size(F,2)] + 80) = F;
disp('Search target using imfilter, this may take some time...')
If = imfilter(I, F);
[maxval ind] = max(If(:));
[y x] = ind2sub(size(If), ind);
imshow(I)
hold on
plot(x, y, 'rx')

Use normxcorr2(). See my demo of it, attached.
