title: How multiple images are stitched
body: <p>I was trying to learn the theory behind image stitching and found articles on how to stitch only two images. I read many papers on stitching such as Lowe who has represented a great paper on image stitching. But one thing is missing always, how are multiple images matched? Is it 1st image with all other images, stitch them, then result of that with remaining set of images? If someone could clear out my doubt it would be great</p>
