Region-restricted rapid keypoint registration

Optics Express, 2009
A two-stage keypoint registration approach is proposed to achieve frame-rate performance, while maintaining high accuracy under large perspective and scale variations. First, an agglomerative clustering algorithm based on an effective edge significance measure is adopted to derive the corresponding regions for keypoint detection.

Electrophysiological Changes in Pediatric Spinal Muscular Atrophy: Results From an Observational Study

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Previous studies of children with spinal muscular atrophy (SMA) have focused on the ulnar and median nerves, while lower‐limb and proximal motor nerves remain insufficiently characterized. This study aimed to evaluate compound muscle action potential (CMAP) amplitudes in upper‐ and lower‐limb motor nerves in children with SMA

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Real‐Time Behavior Recognition Using a Legged Robot for Animal–Robot Interaction

Journal of Field Robotics, EarlyView.
ABSTRACT Animal–robot interaction is an emerging interdisciplinary field that explores the dynamics between animals and robotic systems, as well as the design principles for effective engagement. While previous approaches have investigated animal responses to robotic stimuli, they have yet to integrate artificial intelligence (AI) for real‐time ...

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.

Robotic Cell Micromanipulation Skill Learning via Imitation‐Enhanced Reinforcement Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Humans can learn complex and dexterous manipulation tasks by observing videos, imitating and exploring. Multiple end‐effectors manipulation of free micron‐sized deformable cells is one of the challenging tasks in robotic micromanipulation. We propose an imitation‐enhanced reinforcement learning method inspired by the human learning process ...
