It's using imellipse that does the job for 5 region, but only the last region is displayed. How to do for each region save to array, for each array draw it out, then for each object in array draw it out. Thanks

N = 5 ;
I = imread('13170.jpg');
im = imshow(I);
for i = 1:N
e = imellipse(gca);% now pick ROI
setColor(e, 'red');
position = wait(e);
    BW = createMask(e,im);% get BW mask for that ROI
    BW(:,:,2) = BW;
    BW(:,:,3) = BW(:,:,1);
    ROI = I;
    ROI(BW == 0) = 255;
end
figure(i)
imshow(ROI,'Border','tight');

clc; clear all;
N = 5 ;
I = imread('junk.jpg');

iwant = cell(N,1) ;
for i = 1:N
    im = imshow(I);
    e = imellipse(gca);% now pick ROI
    setColor(e, 'red');
    % position = wait(e);
    BW = createMask(e,im);% get BW mask for that ROI
    BW(:,:,2) = BW;
    BW(:,:,3) = BW(:,:,1);
    ROI = I;
    ROI(BW == 0) = 255;
    iwant{i} = ROI ;
end
for i = 1:N
    figure
    imshow(iwant{i},'Border','tight');
end

Thanks for helping me. How can I show total 5 region in the same figure?
