On two-stage james-stein sstimators
Communications in Statistics. Part C: Sequential Analysis, 1983In the context of minimum risk (point) estimation of the mean vector of a multivariate normal distribution, based on the James-Stein and an allied rule, a two-stage procedure is considered, and the relative risk efficiency results are studied.

A Two-Stage Correlation Method for Stereoscopic Depth Estimation
2010 International Conference on Digital Image Computing: Techniques and Applications, 2010The computation of stereoscopic depth is an important field of computer vision. Although a large variety of algorithms has been developed, the traditional correlation-based versions of these algorithms are prevalent. This is mainly due to easy implementation and handling but also to the linear computational complexity, as compared to more elaborated ...

Two-stage Kalman estimator with unknown exogenous inputs
Automatica, 1999The paper presents a two-stage estimator for bias and state filtering in discrete-time stochastic linear systems affected by unknown inputs of disturbances. It is shown that the state estimator can be expressed as a sum of a bias-free state estimator and the optimal estimator of constant bias.

Estimation of Synchrophasor with Two-Stage ADALINE
2012 International Symposium on Computer, Consumer and Control, 2012The estimation of synchrophasor is of great concern for power quality and protection in power system. Once the power frequency deviation is present, the phasor would undergo a rotation in the complex plane. This phenomenon will introduce difficulty for the interconnection of power grids and distributed generation systems. In this paper, a synchrophasor

two-stage least squares and the k-class estimator
1987Two-stage least squares (TSLS) is a method of estimating the parameters of a single structural equation in a system of linear simultaneous equations. The TSLS estimator was proposed by Theil (1953a, 1961) and independently by Basmann (1957). The early work on simultaneous equation estimation was carried out by a group of econometricians at the Cowles ...

Generalized two-stage Kalman estimator
Proceedings of the 36th IEEE Conference on Decision and Control, 2002This paper presents an optimal two-stage estimator for discrete-time stochastic systems subject to disturbances evolving in accordance with a dynamic state equation. The proposed two-stage estimator gives an optimum state estimate expressed as x/sub k/k//sup 1/=x/sub k/k//sup 1/+/spl beta//sub k/k/ x/sub k/k//sup 2/, where x/sub k/k//sup 1/ and x/sub k/

Enhanced Two-Stage Multi-person Pose Estimation
2019In this paper we introduce an enhanced multi-person pose estimation method for the competition of the PoseTrack [6] workshop in ECCV 2018. We employ a two-stage human pose detector, where human region detection and keypoint detection are separately performed.

Two-stage DOA estimation for CDMA multipath signals
Information Sciences, 2012This paper mainly estimates the direction-of-arrival (DOA) of the code-division multiple access (CDMA) signal in a multipath environment using a two-stage procedure. In general, in a multipath environment, signal DOA would nominally be a DOA phenomenon, causing the DOA estimation method to be biased.
