How can I find the connected components of an image and then label them?

So I have this image attached here and bw is of type 512*512 logical.I need to find the connected components of this image and then label them.I have read about 'bwconncomp' but I am unable to get connected components from it.How can I move further?

There are matlab functions:

%compute conn components
CC = bwconncomp(BW);
%label them
L = labelmatrix(CC);

I have used these commands and I am getting the outputs like you can see in the attached pictures below.Actually I need to mark these clouds separately.That is what I need.

[Massimo Zanetti]

THat is correst, clouds are colored differently because they have different labels. Check matrix L values.

[Prachi Sharma]

Ok,is there a way in which I can mark these clouds as number 1,2 and so on?

[Massimo Zanetti]

that is what "labelmatrix" exactly does.

[Prachi Sharma]

Yeah you are right.It is working I checked L values.Thanks a ton. :)

You are welcome :)
