Abstract: The image stitching algorithm using SIFT feature is complicated and hard to handle the seam line as well as ghosting.We proposed a fast image stitching algorithm to eliminate the seam line and ghosting.First,we extracted SIFT features in the given area of the full image.After obtaining the feature correspondences,we used the RANSAC algorithm to compute the homograph matrix H.Then,an integral image without seam line was received by the combination of the best seam line and the improved image fusion algorithm.The experimental results show that the algorithm not only eliminates the seam line and ghosting effectively,but also improves the efficiency of image stitching.
