Semantic segmentation guided feature point classification and seam fusion for image stitching
Journal of Algorithms & Computational Technology, 2021 Image stitching can be employed to stitch images taken from different times, perspectives, or devices into a panorama with a wider view. However, the imaging specification of images to be stitched is strict. If the imaging specification is not satisfied,
