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.

Start by identifying the number of blobs. Are you already able to do that?

I searched and I know this:
if true
[labeledImage, numberOfBlobs] = bwlabel(binaryImage);
but when I want to see for example first blob and I used this code:
if true
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;
