Centroid

Function takes a picture as an argument (suitably should contain only one object whose centroid is to be obtained) and returns the x and y coordinates of its 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.

Adapted from centroid computation in general where the centroid is the center of mass of a body, the spectral centroid is an measure for the brightness of a sound.

Microsoft MapPoint add-in that performs cluster analysis on MapPoint datasets. Cluster results can be drawn as map annotation (centroid pushpins and/or cluster boundary shapes) and exported to Microsoft Excel. MPCluster works with most MapPoint dataset types, including pushpins and shaded areas...

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 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...
