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. Some digital cameras can stitch their photos internally. The image mosaicing is one of the most widely used techniques for semi-automated or automated recovery of original documents from ripped up documents. Reconstruction of hand torn paper documents is a challenging task in forensic and investigation sciences. There are a number of hard and soft constraints that must be observed while stitching images. It is an active research area in the fields of photogrammetric, computer vision, and computer graphics. In this paper, several approaches have been dealt to overcome image stitching problem which are summarized briefly.
