The mean shift algorithm is a well-known statistical method for finding local maxima in probability distributions. Besides filtering and segmentation it is applied in the field of object tracking. There are several approaches that use the mean shift method for locating target objects in video sequences. This paper compares three similar approaches and investigates their performance on different...

In this paper a novel approach for detection of peaks in spectral representations of music signals is proposed. The basic idea is to detect local maxima in any digitized signal and employ statistical techniques for filtering out spurious peaks which are the result of imperfections and noise in spectral representations of music signal.

Standard Mutual Information function contains local maxima, which make against to convergence of registration transformation parameters for automated multimodality image registration problems. We proposed Feature Potential Mutual Information (FPMI) to increases the smoothness of the registration measure function and use Particle Swarm Optimization to search the optimal registration transformati...

Several authors have suggested allowing for unknown latency of the hemodynamic response by incorporation of hemodynamic derivative terms into the linear model for the statistical analysis of fMRI data. In this paper, we show how to use random field theory to provide a P value for local maxima of two test statistics that have been recently proposed for detecting activation based on this analysis.

This paper discusses the construction of perfect reconstruction filter banks using morphological operators. Two concrete examples are given: (i) the morphological Haar wavelet, and (ii) a wavelet decomposition obtained from the lifting scheme which has the nice property that local maxima are being preserved.

genome? To what extent do the particular assumptions made in the analysis (e.g., independence of sites, evolutionary model, same substitution rate across sites) affect the number and type of local maxima? Such questions provide a rich source for investigation into the efciencies of phylogenetic reconstruction methods.

In many problems in science and engineering ranging from astrophysics to geosciences to financial analysis, we know that a physical quantity y depends on the physical quantity x, i.e., y = f(x) for some function f(x), and we want to check whether this dependence is monotonic. Specifically, finitely many measurements of xi and yi = f(xi) have been made, and we want to check whether the results o...

In the characterization of multivariate extreme indices of multivariate stationary processes, multivariate maxima of moving maxima processes, or M4 processes for short, have been introduced by Smith and Weissman. Central to the introduction of M4 processes is that the extreme observations of multivariate stationary processes may be characterized in terms of a limiting max-stable process under q...

A class of criteria for extracting a few number of most interesting sources from their linear instantaneous mixtures is proposed and proved to have the contrast property. Further, solutions which correspond to sources are shown to be local maxima points of the criteria.

Separation has always been an important task in the chemical industry. Even with the recent shift in emphasis and efforts to unify the physical and biological sciences, separation will remain an important workhorse in production and product/process design. The theory of simple distillation and residue curve maps has a long history—roughly 100 years—and has made a significant impact in the way m...
