Generally, coordinates obtained by global positioning systems (GPS) can be applied when
they are transformed into local or national coordinates. The four-and seven-parameter …

Estimating the parameters of sinusoidal signals is a fundamental problem in signal
processing and in time-series analysis. Although various genetic algorithms and their …

A composite signal is generally composed of multiple signals with various frequencies and
amplitudes. Fourier series expansion is one of the examples of such decomposition in sine …

In this paper, we consider the parameters estimation of a model of superimposed
exponential signals in multiplicative and additive noise when some observations are …

This paper present a Improved Algorithm for Image Segmentation System for a RGB colour
image, and presents a proposed efficient colour image segmentation algorithm based on …

In this paper, we propose a method based on maximizing a periodogram-type function for
parameter estimation of a two-dimensional (2-D) mono-component chirp signal model. The …

We consider the (possibly nonlinear) regression model in R^ q R q with shift parameter α α
in R^ q R q and other parameters β β in R^ p R p. Residuals are assumed to be from an …

We consider a nonlinear regression model when the index variable is multidimensional.
Such models are useful in signal processing, texture modelling, and spatio-temporal data …

Robust estimation methods are often used to eliminate or weaken the influences of gross
errors on parameter estimation. However, different robust estimation methods may have …
