You define first the number of clusters into which you want to divide all the data,
and then for each cluster, a representative point (centroid) is chosen. The
distance between each data point and the three centroids is considered as a
criterion for membership. There are some examples available on the Internet in
which the K-means method is applied, and it is totally implemented in JavaScript;
among them I choose one developed by Heather Arthur (https://github.com/

2. Simple. Linear. Iterative. Clustering. Before describing the proposed
acceleration algorithms in detail, we review the conventional SLIC algorithm [3]
after defining some notations. A pixel i in an input image I of size L × M = N is
represented as a feature vector of its color in the CIELAB color space and
position, fi = [li ,ai ,bi ,xi ,yi]T. Similarly, a cluster center Ck is represented with
mean color and center of mass of the cluster, fCk = [lCk ,aCk ,bCk ,xCk ,yCk]T. In
SLIC, ...

If there is a cluster of size k present, then the graph of P (k ) should have a high
sustained peak around the value k. If there is no cluster present, then there
should be no pattern in the graph of P(k). Figure la shows a typical plot of P (k )
for a Poisson data set without a cluster. Figure lb shows a graph of the P (Jk )
function for a Poisson data set that also has a cluster of size six. PCkJ — Without

All of these elements are used as input to a hierarchical clustering algorithm
implemented with an external library4. The distance metric is the pq-gram edit
