Sentence examples for displacement estimation and from inspiring English sources
The control strategy is chosen in order to drive the piezoelectric actuator in charge for accurate tip displacement estimation and reduction of the intrinsic hysteresis of material.
The proposed SCA-based approach has two main stages: modal matrix estimation and modal displacement estimation.
Three novel ARFI imaging methods, pre-excitation displacement estimation, parallel-transmit excitation and parallel-transmit tracking, were implemented.
Most of the assessments of the performance seem to have relied on measuring various parameters of impact (e.g. force, velocity and tissue displacement), estimation of injury size days or weeks after injury and assessment of behaviour usually using the BBB [15] observational scale.
However, transthoracic imaging is a challenging environment for displacement estimation due to poor SNR, acoustic clutter and complex cardiac motion.
The package presents improved algorithms for mean square displacement estimation, controlling effects of frame loss during recording, and a novel numerical conversion method using segmentwise interpolation, decreasing the conversion error from about 100% to the order of 1%.
The method was tested on simulated images and the results show that absolute displacement estimation error was reduced by a factor of 4 compared to classical block matching.
In this paper, we present algorithms for efficient GPU parallel processing of two widely used tools in ultrasound: cubic spline interpolation and Loupas' two-dimensional autocorrelator for displacement estimation.
This iterative approach is shown to decrease the absolute error of the displacement estimation by a factor of 1.4 when passing from 1 to 2 iterations.
A Kalman filter improves the estimations and the Ackermann steering restriction is applied so the vehicle follows a constrained trajectory, which improves the camera displacement estimation obtained from a PnP algorithm.
This paper proposes a novel method to derive reservoir level variation data with displacement estimation simultaneously for the mechanism explanation of deformations.
