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 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 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 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.

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.

Propagation of Errors in Colorimetric Transformations

Journal of the Optical Society of America, 1959
A common colorimetric transformation is a homogeneous linear transformation of tristimulus values from one primary system to another. The transformation coefficients are obtained by spectrophotornetry and/or visual color matching and consequently are subject to certain errors.

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 ...

Chromosome error propagation and cancer

Trends in Genetics, 1989
A general characteristic of tumour cells is their unstable karyotype. It is suggested here that maintenance of the normal diploid cell depends on the presence of two copies of specific genes; a change in gene dosage of one or more of these genes, by chromosome nondisjunction or rearrangement, may trigger a general loss of accuracy in chromosome ...

Propagation of Errors in Spectrophotometric Colorimetry

Journal of the Optical Society of America, 1953
An important part of the basis of instrumental colorimetry, namely, the uncertainty of spectrophotometric data, has been neglected in the investigations of color and color specification. The uncertainty of measurement of spectral data results from recurrent and random fluctuations such as slit-width and stray-energy effects and photometric-scale and ...
