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

image processingMATLAB

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

Try this:

bw = imread('bw.png');
if ndims(bw) > 1
	bw = bw(:,:,1);
end
% Threshold
bw = bw > 128;
subplot(1, 2, 1);
imshow(bw, []);
% Fill holes
bw = imfill(bw, 'holes');
% Get areas
props = regionprops(bw, 'Area');
sortedAreas = sort([props.Area], 'descend')
% Looks like we need to throw away any blobs less than 1000 pixels or so
bw = bwareaopen(bw, 1000);
subplot(1, 2, 2);
imshow(bw);
% Count the blobs
[labeledImage, numBlobs] = bwlabel(bw);
fprintf('Found %d shapes.\n', numBlobs);

Hi,

If my understanding of your question is not wrong.

Irgb = imread('rhsr9t.jpg');
Icrop = imcrop(Irgb,[75 25 670 500]);
Igray = rgb2gray(Icrop);
Ibw = im2bw(Igray,graythresh(Igray));
Iarea = bwareaopen(Ibw,300);
Idilate = imdilate(Iarea,strel('line',10,0));
stat = regionprops(Idilate,'Centroid');
linecoor = [0                 stat.Centroid(2);
            stat.Centroid(1)  stat.Centroid(2);
            size(Irgb,2)      stat.Centroid(2)];
imshow(Icrop); hold on
plot(stat.Centroid(1),stat.Centroid(2),'ro','markersize',10,'linewidth',2);
line(linecoor(:,1),linecoor(:,2),'linewidth',2,'color','g');

And the result :
