Enhanced Indoor Scene Recognition and Localization for Pedestrian Using Minimum Matching Group of Pedestrian Steps

Indoor positioning acts as a fundamental infrastructure for Internet of Things (IoT) and artificial intelligence systems. However, conventional landmark-based positioning methods suffer from degraded performance in complex indoor scenarios, where complicated path layouts and varied pedestrian behaviors hinder reliable...

Robust structure from motion for aerial-ground images via detector-free feature matching and multi-view track refinement

Integrated 3D reconstruction from aerial-ground images is essential for generating high-precision urban 3D models, yet severe variations in viewpoint, scale, and rotation make robust feature matching highly challenging. To address these limitations, this study introduces a rotation-robust detector-free matching network...
