how to extract color as feature vector from an image using color coherence vector?

Hi, I want to extract color as feature vector using color coherence vector (CCV) method. For this, I have downloaded the MATLAB code for CCV from the link " http://in.mathworks.com/matlabcentral/fileexchange/47935-color-coherence-vector ". After running the program I am getting a 2 by 27 matrix as output. I want to know whether I can use this matrix as color feature vector or not? And am I getting the correct output? If not how can I modify the code? Please help me as soon as possible. I am using the downloaded code in this way-

clc;
clear all;
close all;
I= imread('peppers.png');
CCV=getCCV(I);
