Image stitching or photo stitching is a technique used to create high-resolution panoramic images from multiple photographs. Stitching is the process of seamlessly stitching together several detailed photographs into one large, high-resolution image
. Stitching programs use a variety of algorithms and fixation points to stitch detailed images together into a single image without cutting edges, taking into account different exposures and dynamic ranges. The quality of the stitching depends on the pixel and image alignment and the exact determination of the reference points.
Stitching is ideal for photos that are beyond the normal focal length of digital cameras. The photos can be displayed with their own aspect ratio in a super resolution without distortion. Besides displaying panoramic photos, stitching technique is also used in art photography, medical imaging and satellite photography.
