Random Walker Framework for Sensor-Based Echocardiography Fusion
IEEE Access, 2018 Image fusion techniques in 3-D echocardiography attempt to improve the field-of-view by combining multiple 3-D ultrasound (3-DUS) volumes. Echocardiography fusion techniques are mostly based on either image registration or sensor tracking.

Optical lock-in particle tracking in optical tweezers
Optics Express, 2013 We demonstrate a lock-in particle tracking scheme in optical tweezers based on stroboscopic modulation of an illuminating optical field. This scheme is found to evade low frequency noise sources while otherwise producing an equivalent position measurement to continuous measurement.

Computer generated optical sound tracks
Proceedings of the December 5-7, 1972, fall joint computer conference, part I on - AFIPS '72 (Fall, part I), 1972 For several years various groups at the Los Alamos Scientific Laboratory have been using computer generated motion pictures as an output medium for large simulation and analysis codes. Typically, the numerical output from one simulation run is so large that conventional output media are ineffective.
