In this am segmented the selected region,I have done this twice,i.e used a for loop for two times and extracted features ,i get same image for 2 iterations but features are entirely different wen i summed them up it goes to aroung 220,y i get like this,it should be near to 0, kindly help

the code i used for GLCM is

GLCM2 = graycomatrix(seg_image,'Offset',[2 0;0 2]);

 out= GLCM_Features1(GLCM2,0)

I used all 17 features
