Single view silhouette fitting techniques for estimating tennis racket position [PDF]

, 2017
Stereo camera systems have been used to track markers attached to a racket, allowing its position to be obtained in three-dimensional (3D) space. Typically, markers are manually selected on the image plane, but this can be time-consuming.

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

Journal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Markerless Motion Capture with Structure Estimation Capability

Journal of Robotics and Mechatronics, 2008
We present a markerless motion capture system able to determine the kinematic structure while measuring joint movement. In addition to volume data, we also use texture data to precisely measure the degrees of freedom that do not affect the shape, e.g., pronation/supination angles of the forearm and shank. We first obtain topology using a Reeb graph and

Rhizobial motility preference in root colonization of Medicago truncatula

New Phytologist, EarlyView.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Rule Of Thumb: Deep derotation for improved fingertip detection [PDF]

, 2015
We investigate a novel global orientation regression approach for articulated objects using a deep convolutional neural network. This is integrated with an in-plane image derotation scheme, DeROT, to tackle the problem of per-frame fingertip detection in

Peering into the world of wild passerines with 3D‐SOCS: Synchronized video capture and posture estimation

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 339-356, February 2026.
Abstract Collection of large behavioural data‐sets on wild animals in natural habitats is vital in ecology and evolution studies. Recent progress in machine learning and computer vision, combined with inexpensive microcomputers, has unlocked a new frontier of fine‐scale markerless measurements.

Comparison of Marker-Based and Markerless Motion Capture Systems for Measuring Throwing Kinematics

Biomechanics
Background: Marker-based motion capture systems are commonly used for three-dimensional movement analysis in sports. Novel, markerless motion capture systems enable the collection of comparable data under more time-efficient conditions with higher ...

Validation of a Trained AI Imaging Model for Detecting Diabetic Foot Deformities

International Wound Journal, Volume 23, Issue 2, February 2026.
ABSTRACT Diabetes is a leading cause of morbidity and mortality, contributing to complications such as cardiovascular disease, kidney failure and lower‐limb amputations. Diabetic foot complications, such as structural deformities, ulceration and infection, present significant risks, necessitating early detection and intervention.
