How to stitch overlapping images correctly?

I intend to stitch several overlapping images, I have started with two of them. The functions imregconfig and imregister seem to rotate the image perfectly. But still a bit of translation is needed to get a correct image registration. I have attached results before and after image registration. How can it be achieved so that I get a stitched image?
Here is the relevant portion of the code:
im1=im1(1:2:end,1:2:end,:); im2=im2(1:2:end,1:2:end,:);
grayImage1 = rgb2gray(im1); grayImage2 = rgb2gray(im2);
grayImage1 = medfilt2(grayImage1,[3 3]); grayImage2 = medfilt2(grayImage2,[3 3]);
[optimizer, metric] = imregconfig('monomodal');
grayImage2= imregister(grayImage2,grayImage1,'affine',optimizer,metric);
figure; imshowpair(im1,im2,'blend')
figure, imshowpair(grayImage1,grayImage2,'blend');
