Image mosaic is brought up for improving the visual field of common camera which cannot fulfill practical requirement
of ultra-wide-angle panoramic images. As widely known, to get mosaic images, two main steps should be considered,
namely image alignment and stitching. Image stitching algorithms create the high-resolution photo-mosaics used to
produce today’s digital maps and satellite photos. In this paper, an image stitching process to detect and eliminate the
pixel merges is improved and compared with some popular image stitching algorithms.
