sir i am talking about plots of images.hope you are getting me comparison simply means in context of shape of image.sir i want to compare two images of different sample and identify the type on basis of shape

Extract the blue channel, threshold, call imclearborder to get rid of partial cells, label, then call regionprops and ask for various shape parameters like area, perimeter, EulerNumber, Solidity, etc.

You could try morphometrics: http://en.wikipedia.org/wiki/Morphometrics No, I don't have any MATLAB code for that. Or you could calculate other things like the circularity =Perimeter^2/(4*pi*area), Solidity, major and minor axes, etc. I think I've done a great deal for you. Surely you must expect to do some of this yourself and not have me write the whole thing for you for free. I'll give you one more snippet to calculate circularities.
allPerimeters = [blobMeasurements.Perimeter];
allAreas = [blobMeasurements.Area];
circularities = appPerimeters .^ 2 ./ (4*pi*allAreas);
% Perfect circles will be 1 and gets bigger the more tortuous the border is.
