Image Alignment and Stitching: A Tutorial1Richard SzeliskiLast updated, December 10, 2006Technical ReportMSR-TR-2004-92This Tutorial reviews Image Alignment and Image stitching algorithms. Image align-ment algorithms can discover the correspondence relationships among images withvarying degrees of overlap. They are ideally suited for applications such as videostabilization, summarization, and the creation of panoramic mosaics. Image stitch-ing algorithms take the Alignment estimates produced by such registration algorithmsand blend the images in a seamless manner, taking care to dealwith potential prob-lems such as blurring or ghosting caused by parallax and scene movement as well asvarying Image exposures. This Tutorial reviews the basic motion models underlyingalignment and stitching algorithms, describes effective direct (pixel-based) and fea-ture-based Alignment algorithms, and describes blending algorithms used to produceseamless mosaics. It closes with a discussion of open research problems in the ResearchMicrosoft CorporationOne Microsoft WayRedmond, WA 98052 shorter version of this report appeared in Paragios, al.

Dec 10, 2006 · Algorithms for aligning images and stitching them into seamless photo-mosaics are among the ... Section 3 discusses how direct pixel-to-pixel comparisons combined with gradient descent (and other optimization techniques) can be used to estimate these parameters. Section 4 discusses how ... Having defined our coordinate system, we can now ...
