# MATLAB: I have plotted a image using imshow(Image). Now I placed “hold on” command. I have drawn the boundaries of each object in the image as given in code below. How to capture the new image with boundaries drawn in the plot into an array of pixels ?

[B,L,N] = bwboundaries(Image);
imshow(Image); hold on;
for k=1:length(B),
    boundary = B{k};    if(k > N)        plot(boundary(:,2),boundary(:,1),'g','LineWidth',2);    else        plot(boundary(:,2),boundary(:,1),'r','LineWidth',2);    endend

for k=1:length(B)    boundary = B{k};    for k = 1 : size(boundary, 1)        x = boundary(:,2); % Column        y = boundary(:,1); % Row        boundaryImage(y, x) = 255;    endend
