XStreamVGGT: Extremely Memory‐Efficient Streaming Vision Geometry Grounded Transformer With KV Cache Compression

Journal of the Society for Information Display, EarlyView.
XStreamVGGT enables memory‐efficient streaming 3D inference by jointly pruning and quantizing the KV cache. It reduces memory by 4.42× and accelerates inference by 5.48×, with negligible performance loss on depth, reconstruction, and pose estimation, overcoming the unbounded cache growth of StreamVGGT.

A Novel Feedforward Youla Parameterization Method for Avoiding Local Minima in Stereo Image-Based Visual Servoing Control

Applied Sciences
In robot navigation and manipulation, accurately determining the camera’s pose relative to the environment is crucial for effective task execution. In this paper, we systematically prove that this problem corresponds to the Perspective-3-Point (P3P ...

The Automated Vestibular Rehabilitation System: Normative Data From a Machine Vision‐Guided Platform

The Laryngoscope, EarlyView.
The Automated Vestibular Rehabilitation System (AVRS) is a machine vision‐based tool designed to increase accessibility to vestibular rehabilitation therapy by automating exercise delivery and tracking head‐eye movements in real time. In n = 40 healthy adults, the AVRS accurately measured vestibulo‐ocular reflex (VOR) gain values near physiologic norms

A lightweight clear liquid optical chamber baited remote underwater video system for monitoring fish in turbid coastal wetlands

Limnology and Oceanography: Methods, EarlyView.
Abstract Clear liquid optical chamber baited remote underwater video systems (CLOC‐BRUV) are an effective option for assessing fish assemblages in turbid water, but current designs are limited by their large size and high operational costs. We developed a lightweight CLOC‐BRUV unit and evaluated its performance through proof‐of‐concept trials and field

Quantitative Analysis of Locus Coeruleus Neurons and Thalamic Noradrenergic Axons in a Progressive 1‐Methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine Monkey Model of Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease is mainly characterized by dopaminergic neurodegeneration in the substantia nigra pars compacta (SNc) and α‐synuclein accumulation. The locus coeruleus (LC) is also affected in Parkinson's disease and linked to some nonmotor symptoms, but the extent and timing of its degeneration remain unclear.

Development of a Stereo Vision Measurement System for a 3D Three-Axial Pneumatic Parallel Mechanism Robot Arm

Sensors, 2011
In this paper, a stereo vision 3D position measurement system for a three-axial pneumatic parallel mechanism robot arm is presented. The stereo vision 3D position measurement system aims to measure the 3D trajectories of the end-effector of the robot arm.

Macroscale Gradient‐Informed Neural Oscillation Topography in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is characterized by large‐scale disruptions in beta and gamma oscillations. Although subcortical beta power is an established biomarker for current adaptive deep brain stimulation (aDBS), it may not fully capture the global pathophysiological burden and the macroscale hierarchical reorganization of the ...

Phyllocephalum keralense (Asteraceae) a new species from southern Western Ghats of Kerala, India

Nordic Journal of Botany, EarlyView.
A new species of Phyllocephalum is described and illustrated from Palakkad district of Kerala, India. The new species shows similarity to P. rangacharii but differs with respect to key floral traits, viz. ovoid shape of the capitula, involucral bracts in 3 series, inflated receptacle and ovoid 6‐ribbed ovary with 5–6 densely barbellate pappus setae ...
