How to save image in MATLAB, that is the output of a loop and has segmented regions?

I am using the JSEG that's available at matworks for the segmentation, and using a image database to run the segmentation for i nnumber of iterations. after this I am trying to save the segmented data into a folder so that I can use that later as input to the rest on my network. As mentioned before I am using the JSEG code available here: https://www.mathworks.com/matlabcentral/fileexchange/64123-jseg-unsupervised-segmentation-of-color-texture-regions-in-images

the output of this code is:

[segmented image, image_with boundary, boundary region]=JSEC(image)

I tweaked the code only at the output level to get the 2 extra outputs that I may be able to utilize them later. Then I am using the following to save the data into my destination folder:

outpath='C:\Users\...\segmented_data';
for i=1:N
    I=readimage(imds,i);
    [J,K,R]=JSEG(I); %to view image use imshow(J)
    filenamea=fullfile(outpath, strcat('imagea', num2str(i),'.jpg'));
    filenameb=fullfile(outpath, strcat('imageb', num2str(i),'.jpg'));
    imwrite(J,filenamea);imwrite(K,filenameb);hold on;DrawLine(R);hold off;
end        

This does save my images into destination folder, however the images that I am naming as K from the code above is not able to show the boundary as it does when I imshow it for every iteration, I realize, I must be using this line wrong, as it cannot be used the same way I might be able to during imshow

hold on;DrawLine(R);hold off;

But I am kind of lost at this point on how to make this happen. Any help is appreciated. thank you
