GAST-FPS: A 3D Keypoint Selection Method with Global Sliding Adaptive Threshold for Keypoint-based 6D Pose Estimation [PDF]
, 2022 The 3D keypoint selection method has a significant impact on the performance of keypoint-based 6D pose estimation. State-of-the-art selection methods do not perform well in textureless regions and uneven texture distribution, therefore, we propose the ...

FREAK: Fast Retina Keypoint [PDF]
2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012 A large number of vision applications rely on matching keypoints across images. The last decade featured an arms-race towards faster and more robust keypoints and association algorithms: Scale Invariant Feature Transform (SIFT)[17], Speed-up Robust Feature (SURF)[4], and more recently Binary Robust Invariant Scalable Keypoints (BRISK)[I6] to name a few.

Image Animation with Keypoint Mask
CoRR, 2021 Motion transfer is the task of synthesizing future video frames of a single source image according to the motion from a given driving video. In order to solve it, we face the challenging complexity of motion representation and the unknown relations between the driving video and the source image.

Adaptive iterative closest keypoint
2013 European Conference on Mobile Robots, 2013 Finding accurate correspondences between overlapping 3D views is crucial for many robotic applications, from multi-view 3D object recognition to SLAM. This step, often referred to as view registration, plays a key role in determining the overall system performance.

Advanced Functional Materials, EarlyView.Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance
