Markerless 3D Face Tracking [PDF]
, 2009 We present a novel algorithm for the markerless tracking of deforming surfaces such as faces. We acquire a sequence of 3D scans along with color images at 40Hz. The data is then represented by implicit surface and color functions, using a novel partition-of-unity type method of efficiently combining local regressors using nearest neighbor searches ...

A Novel Markerless Lung Tumor-Tracking Method Using Treatment MV Beam Imaging
Applied Sciences, 2018 A novel method was developed to track lung tumor motion in real time during radiation therapy with the purpose to allow target radiation dose escalation while simultaneously reducing the dose to sensitive structures, thereby increasing local control ...

Markerless Eye-Hand Kinematic Calibration on the iCub Humanoid Robot
Frontiers in Robotics and AI, 2018 Humanoid robots are resourceful platforms and can be used in diverse application scenarios. However, their high number of degrees of freedom (i.e., moving arms, head and eyes) deteriorates the precision of eye-hand coordination.

Single Camera-Based Remote Physical Therapy: Verification on a Large Video Dataset
Applied Sciences, 2022 In recent years, several systems have been developed to capture human motion in real-time using common RGB cameras. This approach has great potential to become widespread among the general public as it allows the remote evaluation of exercise at no ...

2D Markerless Gait Analysis [PDF]
, 2009 We present a 2D gait analysis system which is completely markerless and extracts kinematic information by analyzing video sequences obtained from an RGB video camera. These properties make the proposed approach particularly suitable in medical contexts where visual gait observation is still a recognised procedure or the invasiveness and high costs of ...

Vision-Based Markerless Gaming Interface [PDF]
, 2009 The paper proposes a novel human machine interface for gaming applications based on computer vision. The key idea is to allow the user to interact with the game by simply moving a hand-held consumer grade camera. Detection of natural features in the incoming video stream avoids instrumenting the scene with optical markers while preserving real-time ...
