How to Capture objects in big image and divided them to small images?

Hi,

I stuck at my study now.

I have one example image. ( http://i42.tinypic.com/b653er.jpg) From this image, I would like to separate these five small objects in the picture to be five small images.

How can I do this. I need your help please.

I am looking forward to hear from you. Thank you very much.

This code works just for this image only

Irgb = imread('b653er.jpg');
Igray = rgb2gray(Irgb);
Ibw = im2bw(Igray,graythresh(Igray));
Ifill = imfill(Ibw,'holes');

%clear the lines
Ihor = imopen(Ifill,strel('line',5,0));
Iver = imopen(Ihor,strel('line',5,90));

Ilabel = bwlabel(Iver);
stat = regionprops(Ilabel,'BoundingBox');
for x = 1 : numel(stat)
    bb = stat(x).BoundingBox;
    Icrop{x} = imcrop(Irgb,bb);
    subplot(numel(stat),1,x); imshow(Icrop{x});
end

Hello, I need to separate the roof, smoke bay, windows, wall and door. I tried to applied the same code for this image. But it seems like nothing happen. Here is the image.

Or is there any other way to separate those thing?

Of course not. Did you see the first line of his answer that said "This code works just for this image only" ? And besides, his code does not do texture segmentation which is what you need.

I just realized it. My mistake. Sorry. So, may I know how can solve my problem? What should I do now since I a newbie in image processing.

Look at section 8.8 here. Pick one, code it up, then create a brand new discussion and attach your code, your image, and your question.
