A study of Cramer-Rao bounds on object shape parameters from scattered field
نویسندگان
چکیده
We have studied the Cramér–Rao bounds (CRB’s) on size and orientation of a known object using the scattered (acoustic or electromagnetic) field. A circular array of transievers surrounding the object under test is proposed. The CRB’s are theoretically derived and compared with the mean square errors computed via Monte Carlo simulations. The CRB’s are found to increase rapidly with wavelength. For reliable estimates, the wavelength of illumination must be smaller than the size of the object.

Cramer-Rao bounds for parametric shape estimation in inverse problems
We address the problem of computing fundamental performance bounds for estimation of object boundaries from noisy measurements in inverse problems, when the boundaries are parameterized by a finite number of unknown variables. Our model applies to multiple unknown objects, each with its own unknown gray level, or color, and boundary parameterization, on an arbitrary known background. While such...
متن کاملCramer-Rao Bounds for Nonparametric Surface Reconstruction from Range Data
The Cramer-Rao error bound provides a fundamental limit on the expected performance of a statistical estimator. The error bound depends on the general properties of the system, but not on the specific properties of the estimator or the solution. The Cramer-Rao error bound has been applied to scalarand vector-valued estimators and recently to parametric shape estimators. However, nonparametric, ...
متن کاملImproved Cramer-Rao Inequality for Randomly Censored Data
As an application of the improved Cauchy-Schwartz inequality due to Walker (Statist. Probab. Lett. (2017) 122:86-90), we obtain an improved version of the Cramer-Rao inequality for randomly censored data derived by Abdushukurov and Kim (J. Soviet. Math. (1987) pp. 2171-2185). We derive a lower bound of Bhattacharya type for the mean square error of a parametric function based on randomly censor...
متن کاملA study of a nonlinear filtering problem for tracking an extended target
The paper presents an analysis of a nonlinear filtering problem corresponding to tracking of an extended target whose shape is modelled by an ellipse. The measurements of target extent are assumed to be available in addition to the usual positional measurements. Using Cramer-Rao bounds we establish the best achievable error performance for this highly nonlinear problem. The theoretical bounds a...
متن کاملToward a Model-Based Bayesian Theory for Estimating and Recognizing Parameterized 3-D Objects Using Two or More Images Taken from Different Positions
A new approach is introduced to estimating object surfaces in three-dimensional space from two or more images. A surface of interest here is modeled as a 3-D function known up to the values of a few parameters. Although the approach will work with any parameterization, we model objects as patches of spheres, cylinders, planes, and general quadrics-primitive objects. Primitive surface estimation...
