Artwork Identification for 360-Degree Panoramic Images Using Polyhedron-Based Rectilinear Projection and Keypoint Shapes

摘要: With the increased development of 360-degree production technologies, artwork has recently been photographed without authorization. To prevent this infringement, we propose an identification methodology for images. We transform image into a three-dimensional sphere and wrap it with polyhedron. On sphere, several points are located on polyhedron to determine width, height, direction rectilinear projection. The is divided transformed projected images reduce adverse effects from distorted panoramic image. also method improving precision at highly position using difference keypoint shapes. After applying proposed methods, by 45% that displayed 79-inch monitor in seriously features were generated scale-invariant feature transformations.
