ABSTRACT: This work deals with some problems of using clustering techniques (KM, KHM etc.) in
colour image quantisation. The authors proposed a new modified Mirkin’s algorithm for centroids initial-
ization in clustering. This approach places the cluster centroids in outlier points (colours) and takes into
account the small clusters, sometimes representing colours important for proper perception of quantised
image. These images were ev ...
