Markerless motion capture of man-machine interaction

2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008
This work deals with modeling and markerless tracking of athletes interacting with sports gear. In contrast to classical markerless tracking, the interaction with sports gear comes along with joint movement restrictions due to additional constraints: while humans can generally use all their joints, interaction with the equipment imposes a coupling ...

A Methodology for Multi-Camera Surface-Shape Estimation of Deformable Unknown Objects

Robotics, 2018
A novel methodology is proposed herein to estimate the three-dimensional (3D) surface shape of unknown, markerless deforming objects through a modular multi-camera vision system.

Development of a Tool for High‐Efficiency, Markerless and Iterative Genome Editing in Shouchella clausii

Microbial Biotechnology, Volume 19, Issue 2, February 2026.
Shouchella clausii, a spore‐forming Gram‐positive bacterium with a long‐standing use as probiotic, has long been considered genetically intractable. This study introduces a high‐efficiency electroporation protocol and a versatile Golden Gate‐compatible shuttle vector (pM4B522), enabling precise, scarless and iterative genome editing in both S.

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.

Marker Data Enhancement For Markerless Motion Capture

IEEE Transactions on Biomedical Engineering
AbstractObjectiveHuman pose estimation models can measure movement from videos at a large scale and low cost; however, open-source pose estimation models typically detect only sparse keypoints, which leads to inaccurate joint kinematics. OpenCap, a freely available service for researchers to measure movement from videos, addresses this issue using a ...

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.

Occlusion-Robust Markerless Surgical Instrument Pose Estimation

Healthcare Technology Letters
Abstract The estimation of the pose of surgical instruments is important in Robot‐assisted Minimally Invasive Surgery (RMIS) to assist surgical navigation and enable autonomous robotic task execution. The performance of current instrument pose estimation methods deteriorates significantly in the presence of partial tool visibility ...

Quantitative Assessment of Upper Limb Ataxia Using a Virtual Reality‐Based Evaluation System

Annals of Clinical and Translational Neurology, Volume 13, Issue 1, Page 180-192, January 2026.
ABSTRACT Objective Cerebellar ataxia impairs coordination and balance, reducing quality of life. Conventional clinical scales, including the Scale for the Assessment and Rating of Ataxia (SARA) and the International Cooperative Ataxia Rating Scale (ICARS), are widely used to assess ataxia but are limited by subjectivity and inter‐rater variability ...

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 ...
