CNN-based 3D Pose Estimation for Weakly Textured Rotationally Symmetric Targets

Current 3D pose estimation methods face challenges in handling rotationally symmetric objects and generalizing to unseen objects, which limits their real-world applicability. To address these issues, this paper proposes a novel 3D pose estimation method. First, the distribution of sampled viewpoints is designed based o...

SHALA: Sparse Hierarchical Alignment for Visible-Infrared Vehicle Re-Identification Under Aerial-Ground Viewpoint Gaps

Visible-infrared vehicle re-identification across aerial-ground UAV platforms, where high-altitude and low-altitude views are separated by a large viewpoint gap, supports all-day traffic monitoring and cross-platform target association. However, most existing cross-modal re-identification methods are developed for sing...
