Learning to Detect and Describe a Wireframe

Iván Ferre, Luis Baumela, Iago Suárez

Abstract: Image matching is essential in computer vision for applications like pose estimation, object retrieval, 3D Reconstruction, and SLAM, which typically involve Front-End (detection/description), Middle-End (matching/filtering), and Back-End (integration) stages, all constrained by computational budgets. For efficient on-device inference, sparse Front-End methods represent images as keypoints and lines forming wireframes; however, these elements are typically detected and processed independently.
