Image segmentation refers to segmenting or dividing an image which corresponds to objects or different parts of an object. The segmentation is carried out using K-means clustering algorithm, which is a fast and efficient way to segment an image. K-means is one of the most widely used algorithm. We have implemented a color based image segmentation using Kmeans clustering technique. The K-means a...

For positive definite matrices A and B, the Kubo-Ando matrix power mean is defined as P?(p,A,B)=A1/2(1+(A?1/2BA?1/2)p2)1/pA1/2(p?0). In this paper, for 0?p?1?q, we show that if one of following inequalities f(P?(p,A,B))?f(P?(1,A,B))?f(P?(q,A,B)) holds any then function f operator monotone on (0,?). We also study inverse problem non-Kubo-Ando means with powers 1/2 2. As a consequence, establish ...

It is well known that special Kubo-Ando operator means admit divergence center interpretations, moreover, they are also mean squared error estimators for certain metrics on positive definite operators. In this paper we give a interpretation every symmetric mean. This characterization of the naturally leads to definition weighted and multivariate versions large class means. We study elementary p...
