You do not need the center of the blob to crop it from the image. You need the bounding box.
measurements = regionprops(binaryImage, 'BoundingBox');
croppedImage = imcrop(binaryImage, measurements.BoundingBox);

You're welcome. Thanks for accepting. You don't need my email because if you need help again you can post back here in Answers and possibly get more answers than from just me.

Use regionprops() and ask for Centroid

regionprops should already act that way.
Note: the page you posted, aaaaa.png, has two or more blobs, because it has the grayscale image at the left and the diagram at the right. You need to be operating on just the grayscale image.
