Image stitching, or known as image mosaic, is the process that combines images with overlapped areas to form an image with wide view and high resolution. Image stitching technique has been quickly developed these years. It has become an important branch in digital image processing and has wide applications. Many image stitching methods have been proposed. This article takes investigation on some image stitching techniques, including image registration, seam removal and quality assessment. Most existing related methods are introduced. Experiments are done to show the result of some main methods. At last, the advantages and disadvantages of some existing methods are discussed and some future potential work are pointed out.
