QUALITY ANALYSIS ON RANSAC-BASED ROOF FACETS EXTRACTION FROM AIRBORNE LIDAR DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
RANSAC algorithm is a robust method for model estimation. It is widely used in the extraction of geometry primitives and 3D model reconstruction. However, there has been relatively little comprehensive evaluation in RANSAC-based approach for plane ...

Disrupted Top‐Down Modulation as a Mechanism of Impaired Multisensory Processing in Autistic Children

Advanced Science, EarlyView.
In this work, we show that multisensory integration in autistic children is characterized by attenuated ERP responses and α‐band desynchronization, together with reduced theta‐band communication between parieto‐occipital and frontal regions. The intermediate neural profile observed in unaffected siblings raises the possibility that altered cortical ...

SynAtlas: A Safe and Versatile Platform for Rapid Organ‐Scale Tissue Clearing and 3D Atlas Mapping

Advanced Science, EarlyView.
An orthogonal synergy design principle integrates lipid solubilization, protein hydration modulation, and refractive‐index matching within a unified aqueous clearing system. This modular strategy enables rapid, low‐hazard, and broadly compatible tissue clearing while preserving molecular signals, supporting multiscale three‐dimensional imaging across ...

Distributed State Estimation for Mobile Robots in LiDAR Sensor Networks With Intermittent Inertial Measurements

Advanced Intelligent Systems, EarlyView.
A scalable distributed observer framework for LiDAR sensor networks is presented for robust tracking and pose estimation of mobile robots. By combining adaptable 3D detection, clustering‐based communication reduction, and intermittent inertial fusion, accurate and efficient estimation is achieved under occlusions and sensing constraints, with formally ...

Multirobot Aerial Soft Manipulator for Floating Litter Collection

Advanced Intelligent Systems, EarlyView.
A multirobot aerial manipulator enables autonomous floating litter collection by controlling the shape of a flexible rope equipped with a hook‐based tool. Adaptive rope‐shape planning enhances grasping performance while reducing tension, demonstrating the potential of aerial robots for floating litter removal. Removing floating litter from water bodies
