Real-time reliability measure-driven multi-hypothesis tracking using 2D and 3D features
We propose a new multi-target tracking approach, which is able to reliably track multiple objects even with poor segmentation results due to noisy environments. The approach takes advantage of a new dual object model combining 2D and 3D features through reliability measures. In order to obtain these 3D features, a new classifier associates an object class label to each moving region (e.g. perso...
متن کاملReal-Time 3D Body Pose Tracking from Multiple 2D Images
We present a human body motion tracking system for an interactive virtual simulation training environment. This system captures images using IR illumination and near-IR cameras to overcome limitations of a dimly lit environment. Features, such as silhouettes and medial axis of blobs are extracted from the images which lack much internal texture. We use a combination of a 2D ICP and particle fil...
متن کاملReal-time Facial Feature Tracking from 2d+3d Video Streams
This paper presents a completely automated 3D facial feature tracking system using 2D+3D image sequences recorded by a real-time 3D sensor. It is based on local feature detectors constrained by a 3D shape model, using techniques that make it robust under pose and partial occlusion. Several experiments conducted under relatively non-controlled conditions demonstrate the accuracy and robustness o...
متن کاملRobust Multi-hypothesis 3D Object Pose Tracking
This paper tackles the problem of 3D object pose tracking from monocular cameras. Data association is performed via a variant of the Iterative Closest Point algorithm, thus making it robust to noise and other artifacts. We re-initialise the hypothesis space based on the resulting re-projection error between hypothesised models and observed image objects. This is performed through a non-linear m...
متن کاملReal-time tumor tracking during VMAT radiotherapy treatments based on 2D/3D registration using CBCT projections
Rotational radiotherapy treatments such as volumetric modulated arc therapy (VMAT) can have superior overall quality while having shorter delivery time with respect to conventional intensity modulated radiotherapy (IMRT). As with conventional treatments, intrafractional tumor motion is a major source of uncertainty in dose application. To ensure full tumor coverage the planning target volume (P...
