The Propagation of Errors

2017
Quite often, it is necessary to calculate the value of a quantity that was not measured directly but is expressed on terms of one or more quantities which have been measured and whose means and standard deviations are known. The evaluation of the standard deviation of this quantity is done taking into account the so-called propagation of errors from ...

Error propagation in machine vision

Machine Vision and Applications, 1994
Machine vision systems that perform inspection tasks must be capable of making measurements. A vision system measures an image to determine a measurement of the object being viewed. The image measurement depends on several factors, including sensing, image processing, and feature extraction.

Error propagation in calculated ratios

Clinical Biochemistry, 2007
Calculated quantities that combine results of multiple laboratory tests have become popular for screening, risk evaluation, and ongoing care in medicine. Many of these are ratios. In this paper, we address the specific issue of propagated random analytical error in calculated ratios.Standard error propagation theory is applied to develop an approximate

Error propagation for the Hough transform

Pattern Recognition Letters, 2001
Summary: In this paper, a statistically efficient Hough transform (HT) technique with improved performance in accuracy and robustness is described. The proposed technique analytically computes the uncertainty of each feature point based on image noise, the procedure used for estimating edge orientation, and the specific parametric representation scheme

Error propagation in geometric constructions

Computer-Aided Design, 2000
In this paper we consider error propagation in geometric constructions from a geometric viewpoint. First we study affine combinations of convex bodies: this has many applications concerning spline curves and surfaces defined by control points. Second, we study in detail the circumcircle of three points in the Euclidean plane.

Error Propagation for Large Errors

Risk Analysis, 1987
An essential facet of a risk assessment is the correct evaluation of uncertainties inherent in the numerical results. If the calculation is based on an explicit algebraic expression, an analytical treatment of error propagation is possible, usually as an approximation valid for small errors.

Error propagation in viable cells

Mechanisms of Ageing and Development, 1979
Error propagation is the process, predicted by theoretical models, whereby errors in translating the genetic code will beget fresh errors in successive generations. It has been postulated that error propagation may underly the mortality of cells which display clonal senescence. We have demonstrated the occurrence of error propagation in viable cells of

Error propagation in eigenimage filtering

IEEE Transactions on Medical Imaging, 1990
Mathematical derivation of error (noise) propagation in eigenimage filtering is presented. Based on the mathematical expressions, a method for decreasing the propagated noise given a sequence of images is suggested. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the final composite image are compared to the SNRs and CNRs of the ...

Error propagation in fourier transforms

Mathematics and Computers in Simulation, 1978
Abstract The Fourier transform has long been of great use in simulating mathematical or physical phenomena, especially in signal theory. However the finite length representation of numbers introduces round-off errors in computing. Here, developing a new point of view on the topic, we give an evaluation of the total relative mean square error in the ...

Modeling Error Propagation in Programs

2017 47th Annual IEEE/IFIP International Conference on Dependable Systems and Networks Workshops (DSN-W), 2017
As technology keeps scaling, hardware fault rates are predicted to increase in future computer system. Traditional methods use hardware-only techniques that are energy hungry. Researchers have proposed selective software techniques to tolerate hardware faults at lower costs.
