I developed a code in in MATLAB to detect the motion. I am getting the foreground objects i.e. the objects that are moving in the field. Now I want to create a blob around each detected objects. Also I have to index them with numerals and find the centroid. Please guide me or give me some links :)
 

Kindly go thru the code


clc;
clear;
close all;
InputImage=imread('eight.tif');
subplot(2,2,1);
imshow(InputImage);title('InputImage');
BinaryImage=im2bw(InputImage);
subplot(2,2,2);
imshow(BinaryImage);
ComplementImage=imcomplement(BinaryImage);
subplot(2,2,3);
imshow(ComplementImage);
HolesClearedImage = imfill(ComplementImage,'holes');
subplot(2,2,4);
imshow(HolesClearedImage);title('HolesClearedImage');
[L,Num] = bwlabel(HolesClearedImage)

for i=1:Num
figure;
imshow(L==i);
pause(1)
end

Thanks for your reply but I know this concept. I just want to create a blob (rectangle) around the detected object with an index as well.
