hi everybody I have a homework that I could not solve this.I hope you can help me. I have a binary image that includes some objects. I want to do some process on these object distinc..I thought maybe regionprobs can help me...Is there any idea? for example if this is my image I want to do my process(for example imdilate) on just 3 blob of this objects.
this Image is from result of this link: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial
thanks

I searched and I know this:
if true
[labeledImage, numberOfBlobs] = bwlabel(binaryImage);
end
but when I want to see for example first blob and I used this code:
if true
figure,imshow(labeledImage(1));
end
I couldn't see the first blob :(

thanks dear I found the answer.
this is the answer:
if true
[labeledImage, ~] = bwlabel(binaryImage);
blobMeasurements = regionprops(labeledImage,'all');
numberOfBlobs = size(blobMeasurements, 1);
for i=1: numberOfBlobs
thisBlobsPixels = blobMeasurements(i).PixelIdxList;
m=zeros(512);
m(thisBlobsPixels)=1;
end
