Plotting K Mean Results, K Mean Output Matlab

Experts,

Hope you are fine and doing well, i have the K Mean Implementation which runs fine , Testing Code is given below,

   index_string        = int2str(k);
    Image_Path          = strcat('D:\MS\Research\Classification Model\Research Implementation\EnhancedImage\ROI',index_string,'.jpeg');
    I1                  = imread(Image_Path);
    I=double(I1);
    figure
    subplot(1,3,1)
    imshow(I1)
    subplot(1,3,2)    
   [idx,C] = adaptcluster_kmeans(I);

Now what i want to do is to draw k Mean results pictorially as shown below ,

Can you please provide some help how we can achieve this by using idx and C. I tried as given in matlab k mean demo but did't worked in my case.

Best Regards
