Assessment of Electromagnetic Tracking Accuracy for Endoscopic Ultrasound [PDF]

open access: yes, 2016
Endoscopic ultrasound (EUS) is a minimally-invasive imaging technique that can be technically difficult to perform due to the small field of view and uncertainty in the endoscope position.

Low power, reduced complexity filtering and improved tracking accuracy for GNSS [PDF]

open access: yes, 2014
This thesis addresses the power consumption problems resulting from the advent of multiple GNSS satellite systems which create the need for receivers supporting multi-frequency, multi-constellation GNSS systems.

Accuracy and Reliability of the Visual Assessment of Patellar Tracking [PDF]

open access: yesThe American Journal of Sports Medicine, 2019
Background: Abnormal patellar tracking is described as a “J-sign” when the patella exhibits excessive lateral displacement during active knee extension. Purpose: To determine (1) the accuracy and reliability of the visual assessment of

Tracking MEP installation works [PDF]

open access: yes, 2013
Recent research efforts to improve construction progress tracking has focused on employing emerging technologies such as three dimensional (3D) imaging, including digital photogrammetry and 3D Terrestrial Laser Scanning (TLS). Previous research has shown

Assessing performance of Bayesian state-space models fit to Argos Satellite telemetry locations processed with Kalman Filtering [PDF]

open access: yes, 2014
Argos recently implemented a new algorithm to calculate locations of satellite-tracked animals that uses a Kalman filter (KF). The KF algorithm is reported to increase the number and accuracy of estimated positions over the traditional Least Squares (LS)

Early tracking of informant accuracy and inaccuracy

open access: yesBritish Journal of Developmental Psychology, 2009
Three‐ and four‐year‐old children ( N =131) were tested for their sensitivity to the accuracy and inaccuracy of informants. Children were presented with one of three conditions. In the Accurate‐Inaccurate condition, one informant named objects accurately whereas the other named them ...

Tracking-Optimized Quantization for H.264 Compression in Transportation Video Surveillance Applications [PDF]

open access: yes, 2011
We propose a tracking-aware system that removes video components of low tracking interest and optimizes the quantization during compression of frequency coefficients, particularly those that most influence trackers, significantly reducing bitrate while ...

Measuring human-induced vibrations of civil engineering structures via vision-based motion tracking [PDF]

open access: yes, 2016
We present a novel framework for measuring the body motion of multiple individuals in a group or crowd via a vision-based tracking algorithm, thus to enable studies of human-induced vibrations of civil engineering structures, such as floors and ...

Accuracy of a Fluoroscopy Technique for Assessing Patellar Tracking [PDF]

open access: yes, 2003
Accuracy of a novel fluoroscopy-based method of assessing patellar tracking was determined by comparing the pattern of patellar motion with respect to orientation (flexion, internal rotation, and lateral tilt) and translation (lateral, proximal, and anterior) with the pattern of patellar motion measured using Roentgen Stereophotogrammetric Analysis ...
