Evaluating Classical and Deep Keypoint Detectors for SfM Reconstruction in Arctic UAV Imagery
Nicholas Sansoterra, María G. Lenzano, William Shuart, John E. Anderson, Alper Yılmaz, Charles Toth
Abstract. Structure-from-Motion (SfM) pipelines rely heavily on the detection and matching of repeatable keypoints across images, yet the performance of modern learned feature extractors in challenging environments remains insufficiently understood. This paper evaluates classical…
