Use bwlabel or bwconncomp. See my BlobsDemo: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862

whats the meaning of this code..?
delim = '';
AllowEmptyEntries = false;

Sorry, Rose, somehow I pasted in the wrong link (one for splitstring which is a replacement for John D'Errico's allwords, which he took down). See the correct link in the edited answer above.

There are numerous ways to learn. You can watch Doug Hull's video tutorials on the web site, you can go over the demos and examples in the help, you can read the blogs, particularly Steve on Image Processing (http://blogs.mathworks.com/steve/), buy and read Steve's book, or you can attend instructor-led classes in person. For you, I'd recommend the instructor led classes.
Now, for my BlobsDemo, exactly which line(s) is/are confusing to you? I thought they were all very well explained through the comments, but maybe not.

I gave the methods I thought would be most productive. I think you can find all the major learning methods on the Mathworks web site: http://www.mathworks.com/services/training/. If examples/demos, videos, books, blogs, documentation, and instructor-led training are all not conducive to your way of learning then perhaps you can tell us what way you learn best. Maybe there's a way of learning I forgot to list.
