Description: This tutorial reviews image alignment and image stitching algorithms. Image align-
ment (registration) algorithms can discover the large-scale (parametric) correspon-
dence relationships among images with varying degrees of overlap. They are ideally
suited for applications such as video stabilization, summarization, and the creation
of large-scale panoramic photographs. Image stitching algorithms take the alignment
estimates produced by such registration algorithms and blend the images in a seam-
less manner, taking care to deal with potential problems such as blurring or ghosting
caused by parallax and scene movement as well as varying image exposures. This tu-
torial reviews the basic motion models underlying alignment and stitching algorithms,
describes effective direct (pixel-based) and feature-based alignment algorithms, and
describes blending algorithms used to produce seamless mosaics. It closes with a dis-
cussion of open research problems in the area.
