how to get a blob's Skeleton using opencv ?

Question

Hi Guys,

In my app, I need to track the motion of the human arms.

Now I can get the whole blob of a human body but I don't know how to seperate "arms" from the blob . Some guy in some where said that "skeletonlization" may be used to solve my problem.

so I'd like to know how to get the skeleton of a blob ? off course, If you have other way to solve my problem other than "skeletonlization" please feel free teach me here .

thanks in advance

Depending on the background maybe you can use edge detection?
