Image stitching, also called photo stitching, is the process of merging multiple photographs together to create a single high resolution or panoramic image. Image stitching is most often done via computer using specific software designed to sense areas of overlap and combine them. The overlaps need to be as exact as possible and the exposures identical to elicit a final image with no visible seams. Because the illumination in two separate images could differ, even if the images are taken in quick succession, image stitching could result in seams between the images. Depending on the application, these seams may or may not be significant. In the field of dentistry, photo stitching is often used for x-rays and CAD/CAM images. This is because it’s not possible to organically capture an image of the entire mouth in one sitting; instead, multiple images from different angles must be obtained and fused together.
