Line assisted vision applications in structured environments

Recently, line feature has been used as addition feature in various computer vision applications such as 3D reconstruction and pose estimation, due to the lack of point feature in structured environments. In this paper, we review line assisted vision applications in structured environments: image stitching and segmentation. By showing the qualitative improvement of two applications, we indirectly prove the effectiveness of line feature. We also suggest line-based future research direction in structured environments.
