I want to outline the boundary of the segment image using bwperim() and get the resultant image i.e boundary.jpg, but my aim is to get an output image which outline the region of segment.jpg with different colors link red or green. How it is possible

You can use bwboundaries() and plot() to do that:
hold on;
boundaries = bwboundaries(binaryImage);
numberOfBoundaries = size(boundaries, 1);
for k = 1 : numberOfBoundaries
thisBoundary = boundaries{k};
plot(thisBoundary(:,2), thisBoundary(:,1), 'g', 'LineWidth', 2);
end
hold off;

pic01=imread("1.tiff");
pic1=im2gray(pic01);
i=1;
boundaries=[];
for i=3:7:69;
pic050=im2gray( imread(i+".tiff") );
%pic50=im2gray(pic050);
newpicture=imsubtract(pic01,pic050);
%imshow(newpicture)
level = graythresh(newpicture);
level = 0.1405;
newbinpic = imbinarize(newpicture,level);
%imshowpair(newpicture,newbinpic,'montage')
newbinpic2=bwpropfilt(newbinpic,'perimeter',1);
% imshowpair(newbinpic2,newpicture,'montage');
boundariesi = bwboundaries(newbinpic2);
boundaries=[boundaries; boundariesi];
binaryImage = 0.6< newbinpic2 & newbinpic2<1;
end
figure; imshow(pic01);
hold on
for k=1:length(boundaries)
thisBoundary = boundaries{k};
x = thisBoundary(:,2);
y = thisBoundary(:,1);
plot(x,y,'r-','Linewidth',2);
end
grid off
This is my code until now

Yeah, you could call getdata() or getsnapshot() to get a frame and then analyze it to get the boundaries. Not sure how "real time" it would be -- how many frames per second -- but you could certainly try it.
