67 Prizm Clusters

The STP Percolation program generates occupied lattice sites with probability p and then determines the clusters of occupied sites. The purpose of this program is to demonstrate some of the important properties of percolation, especially near the geometrical phase transition. The default system...

Matlab implementation of the computer model of atrial fibrillation originally published by Gordon Moe and colleagues in [American Heart Journal 1964; 67(2):200-220.] To run the simulation, just type the function name (afib). It accepts no input or output arguments. Several model parameters can be...

This function applies the Delaunay-based image segmentation, which is a fully automated process that does not require initial estimate of number of clusters.The core idea is to apply Delaunay triangulation to the image histogram instead of the image itself. That reduces the sites required to...

This function segments (clusters) an image into object classes, and estimates and corrects for slow varying illumination artifacts. Estimates and corrects for bias field in 3D MRI, streak artifacts in CT, and illumination artifacts in color photos.It's an implementation of the paper of M.N. Ahmed...

Many ant species exhibit the behavior of clustering corpses to form cemeteries. Each ant seems to behave individually, moving randomly in space while picking up or depositing (dropping) corpses. The decision to pick up or drop a corpse is based on local information of the antd-deOaos current...

This small tool selects colors for a number of patches so that no any neighboring pair of patches have the same color. The tool was motivated by representing clusters produced by k-means.http://www.mathworks.com/matlabcentral/fileexchange/19344It can also demonstrate the famous four color map...

The statistics toolbox contains routines for hierarchical clustering, including the cluster routine uses the SAHN tree to group data into clusters. However, the toolbox seems to lack a routine that uses the SAHN tree to describe the hierarchical relationship between those clusters. This routine...

Discriminant Functions is one of statistical technique used in Pattern Recognition for separating classses.This is parametric methods, means, it requires that mean and covariance of class is known. In other words, Probability Density of given class should be known to apply this method.Here, two...

The conventional tree view is a natural way to represent a dendrogram but is only usable for very small trees.Using the interactive power of computers we can build a more compact view. Leaves are represented as points on a grid. Boxes are drawn round the points to represent the hierarchy. It is...
