Documentation>MATLAB API>KMEANS - vl_ikmeans

C = VL_IKMEANS(X,K) returns the centers of a K-means paritioning of the data space X. X must be of class UINT8. C is of class UINT32.

[C, I] = VL_IKMEANS(...) returns the cluster associations I of the data as well.

VL_IKMEANS() accepts the following options:

MaxIters 200

  Maximum number of iterations before giving up (the algorithm stops as soon as there is no change in the data to cluster associations).

Method Lloyd

  Algorithm to use ('Lloyd', 'Elkan').

Verbose
