Image stitching

Two images stitched together. The photo on the right is distorted slightly so that it matches up with the one on the left.

Image stitching or photo stitching is the process of combining multiple photographic images with overlapping fields of view to produce a segmented panorama or high-resolution image. Commonly performed through the use of computer software, most approaches to image stitching require nearly exact overlaps between images and identical exposures to produce seamless results,^[1]^[2] although some stitching algorithms actually benefit from differently exposed images by doing high-dynamic-range imaging in regions of overlap.^[3]^[4] Some digital cameras can stitch their photos internally.
