Centroid

MathEasy Centroid allows you to compute the center of mass which is formed by the intersection of f(x) and g(X) between a given interval. It shows the image of the plate and the mid point (centroid) with a small circle along with its coordinates. It computes the centroid to near accuracy....

The GMM returns the cluster centroid and cluster variances for a family of points if the number of clusters are predefined. The centroid and variance can then be passed to a Gaussian pdf to compute the similarity of a input query point with reference to given cluster.

This function is for training a codebook for vector quantization. The data set is split to two clusters, first, and the mean of each cluster is found (centroids). The disttance of each vector from these centroids is found and each vector is associated with a cluster. The mean of vectors of each...

This is a simple method for silence removal and segmentation of audio streams that contain speech. The method is based in two simple audio features (signal energy and spectral centroid). As long as the feature sequences are extracted, as thresholding approach is applied on those sequence, in...

This is a (small) change to the current fminsearch routine to improve convergence.The current fminsearch selects n additional simplex points based on a small change in each variable. This implementation uses an adaptive procedure to select these n points while maintaining the correct relative...

ClusterLib was designed as an Open Source library that can be used for agglomerative hierarchical clustering. ClusterLib can work with arrays of Java's Double as well as with other custom data types. In principle, any class implementing the DataPoint interface of this library can be used in...

OSM XML to CSV conversion. POI only, polygons (and polylines, but not recommended) are approximated by centroid. Result is a 3-column table with lon, lat and value (for a particular key to be chosen beforehand).

The Okada [1985] model allows to calculate analytic solution for surface deformation due to shear and tensile faults in an elastic half-space. This model is widely used to simulate ground deformation produced by local perturbation like tectonic faults (earthquakes) or volcanic dykes. Given...

This is a single M-file that implements a Nelder-Mead simplex minimizer. It makes use of MATLAB's persistent variables to create a "state machine" implementation. This allows entire minimization programs to be written as MATLAB scripts, as it does not require a function to be defined and passed...
