thanks for your help.... for detecting object i used regionprops(BW). and got the result...
stats = regionprops('table',bw,'Centroid',...
'MajorAxisLength','MinorAxisLength')
centers = stats.Centroid;
diameters = mean([stats.MajorAxisLength stats.MinorAxisLength],2);
radii = diameters/2;

Rather than averaging the major and minor axis lengths, you might want to consider asking for 'EquivDiameter' which is the diameter of a circle with the same number of pixels as your blob.
If I've solved, it then can you please "Accept this Answer"?
