Markerless analysis of front crawl swimming
Journal of Biomechanics, 2011Research on motion analysis of swimmers is commonly based on video recordings of the subject's motion, which are analyzed by manual digitization of feature points by an operator. This procedure has two main drawbacks: it is time-consuming, and it is affected by low repeatability. Therefore, the application of video-based, automatic approaches to motion

RELIVE: A Markerless Assistant for CPR Training
IEEE Transactions on Human-Machine Systems, 2016Cardiopulmonary resuscitation (CPR) is a first-aid key survival technique used to stimulate breathing and keep blood flowing to the heart. Its effective administration can significantly increase the chances of survival in victims of cardiac arrest.

Markerless tracking for mobile augmented reality
2011 IEEE International Conference on Signal and Image Processing Applications (ICSIPA), 2011This work aims to realize a recognition system for markerless tracking in mobile augmented reality. A method based local invariant descriptors is implemented to extract image feature points for natural fiducial identification. This technique is optimized and adapted for a mobile architecture with low resources and deployed on a portable device ...

Experimenting with noise in markerless motion capture
Proceedings of the 2nd International Workshop on Movement and Computing, 2015Visual culture has embraced the visual glitch as just one of many aesthetics associated with digital media. A glitch is often associated with noise in a technological system. Some motion capture systems experience noise and glitches as they process human movement.

Online Smoothing for Markerless Motion Capture
2007Tracking 3D objects from 2D image data often leads to jittery tracking results. In general, unsmooth motion is a sign of tracking errors, which, in the worst case, can cause the tracker to loose the tracked object. A straightforward remedy is to demand temporal consistency and to smooth the result. This is often done in form of a post-processing.

Markerless Tracking for Augmented Reality
2011Augmented Reality (AR) tries to seamlessly integrate virtual content into the real world of the user. Ideally, the virtual content would behave exactly like real objects. This requires a correct and precise estimation of the user’s viewpoint (respectively that of a camera) with respect to the coordinate system of the virtual content.

Markerless Pose Tracking for Augmented Reality
2006In this paper a new approach is presented for markerless pose tracking in augmented reality. Using a tracking by detection approach, we estimate the 3D camera pose by detecting natural feature points in each input frame and building correspondences between 2D feature points.

Markerless Tracking of the Breast
When treating breast cancer, the large soft tissue deformations of the breast can complicate accurate localisation of tumours. This effects initial screening, surgery, and follow up care for patients with breast cancer. While soft tissue mechanics can predict internal deformation, lack of information about the shape and position of the patient and ...openaire +1 more source
