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, although some stitching algorithms actually benefit from differently exposed images by doing HDR (High Dynamic Range) imaging in regions of overlap. Some digital cameras can stitch their photos internally. Image stitching is widely used in today’s world in applications.
