DOI: 10.1109/tip.2022.3175601
Abstract: In this paper, we study the cross-view geo-localization problem to match images from different viewpoints. The key motivation underpinning this task is to learn a discriminative viewpoint-invariant visual representation. Inspired by the human visual system… read more here.

Key.Net: Keypoint Detection by Handcrafted and Learned CNN Filters Revisited
Sign Up to like & getrecommendations! Published in 2022 at "IEEE Transactions on Pattern Analysis and Machine Intelligence"
DOI: 10.1109/tpami.2022.3145820
Abstract: We introduce a novel approach for keypoint detection that combines handcrafted and learned CNN filters within a shallow multi-scale architecture. Handcrafted filters provide anchor structures for learned filters, which localize, score, and rank repeatable features.… read more here.

DOI: 10.1117/1.jei.30.1.013003
Abstract: Abstract. We propose to rely on the wave equation for the detection of repeatable keypoints invariant up to image scale and rotation and robust to viewpoint variations, blur, and lighting changes. The algorithm exploits the… read more here.
