DIAMONDNET: SHIP DETECTION IN REMOTE SENSING IMAGES BY EXTRACTING AND CLUSTERING KEYPOINTS IN A DIAMOND [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Ship detection plays an important role in military and civil fields. Despite it has been studied for decays, ship detection in remote sensing images is still a challenging topic. In this work, we come up with a novel ship detection framework based on the

Vision–Based Positioning of Electric Buses for Assisted Docking to Charging Stations
International Journal of Applied Mathematics and Computer Science, 2022 We present a novel approach to vision-based localization of electric city buses for assisted docking to a charging station. The method assumes that the charging station is a known object, and employs a monocular camera system for positioning upon ...

Rethinking of learning-based 3D keypoints detection for large-scale point clouds registration
International Journal of Applied Earth Observations and Geoinformation, 2022 The main solution for large-scale point clouds registration is to first obtain a set of matched 3D keypoint pairs and then accomplish the point cloud registration task based on these matched keypoint pairs.

Coplanar Repeats by Energy Minimization [PDF]
, 2016 This paper proposes an automated method to detect, group and rectify arbitrarily-arranged coplanar repeated elements via energy minimization. The proposed energy functional combines several features that model how planes with coplanar repeats are ...

sSLAM: Speeded-Up Visual SLAM Mixing Artificial Markers and Temporary Keypoints
Sensors, 2023 Environment landmarks are generally employed by visual SLAM (vSLAM) methods in the form of keypoints. However, these landmarks are unstable over time because they belong to areas that tend to change, e.g., shadows or moving objects.

Keypoint recognition using randomized trees [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2006 In many 3D object-detection and pose-estimation problems, runtime performance is of critical importance. However, there usually is time to train the system, which we will show to be very useful. Assuming that several registered images of the target object are available, we developed a keypoint-based approach that is effective in this context by ...

Learning-Based Pose Estimation of Non-Cooperative Spacecrafts with Uncertainty Prediction
Aerospace, 2022 Estimation of spacecraft pose is essential for many space missions, such as formation flying, rendezvous, docking, repair, and space debris removal. We propose a learning-based method with uncertainty prediction to estimate the pose of a spacecraft from ...

Shape and Viewpoint Without Keypoints [PDF]
, 2020 We present a learning framework that learns to recover the 3D shape, pose and texture from a single image, trained on an image collection without any ground truth 3D shape, multi-view, camera viewpoints or keypoint supervision. We approach this highly under-constrained problem in a "analysis by synthesis" framework where the goal is to predict the ...
