A DFT based alternating projection algorithm for parameter estimation of superimposed complex sinusoids
Estimation of Superimposed Complex Sinusoids Gaurav Sharma and V. U. Reddy Department of Electrical Communication Engineering Indian Institute of Science Bangalore 560 012, INDIA Abstract In this paper, we consider the alternating projection algorithm suggested by Ziskind and Wax [13] for parameter estimation of superimposed complex sinusoids (cisoids) embedded in noise, and show how the object...
متن کاملApplication of Model-Based Estimation to Time-Delay Estimation of Ultrasonic Testing Signals
Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...
متن کاملانجام یک مرحله پیش پردازش قبل از مرحله استخراج ویژگی در طبقه بندی داده های تصاویر ابر طیفی
Hyperspectral data potentially contain more information than multispectral data because of their higher spectral resolution. However, the stochastic data analysis approaches that have been successfully applied to multispectral data are not as effective for hyperspectral data as well. Various investigations indicate that the key problem that causes poor performance in the stochastic approaches t...
متن کاملPose Estimation via Gauss-Newton-on-manifold
We present a Gauss-Newton-on-manifold approach for estimating the relative pose (position and orientation) between a 3D object and its projection on a 2D image plane from a set of point correspondences. The pose estimation problem is formulated as an optimization over three rotation parameters on the intersection of the manifold of the rotation matrices and a cone constraint on these matrices t...
متن کاملGauss-newton-on-manifold for Pose Estimation
We consider the task of estimating the relative pose (position and orientation) between a 3D object and its projection on a 2D image plane from a set of point correspondences. Our approach is to formulate the task as an unconstrained optimization problem on the intersection of the special orthogonal group and a cone, and exploit as much as possible the geometry of the underlying parameter space...
