I am wondering is there any open source C++ lib can do this.

Could any function in OpenGl do this non-trivial task?

Or I have to do it from the groud up again?

  Please do not ask your question in the subject line, especially given that
it's such a long and complicated one.

...and may I add a suggestion to not ask the question in the subject 
line in the right newsgroup, as well?  comp.graphics.api.opengl is the 
right one if you need OpenGL, or just comp.graphics.algorithms if you 
need somebody's help on devising one (algorithm, that is)

Thanks!

Thus, there is no easy open source for this problem in C++. 
Am I guessing wrong ?

<shrug> I have no idea.  But if *I* were to try to find a solution, I'd 
be looking *elsewhere*.  comp.lang.c++ is not a repository of all open 
source solutions for all possible problems that can be implemented in C++.

If a language does not have a smart library then it is really tedious
to do everything from the ground up again. 

OK, I'll use the Simple-Directmedia Library to play with real 3D stereo
graphics.

Generally speaking, there is no such thing as "a smart library" for 
every possible future problem that people haven't yet encountered, not 
to mention to satisfy every possible requirement from every potential 
user of such a library, so there *always* be somebody contesting the 
"smartness" of that library.

I have to separate the background still objects and the moving or interactive foreground objects such as humans and animals first. 

Thus a good and fast edge tracing algorithm is necessary. 

Any suggestions?

I have to perform edge tracing of sub-sampled images first. 

The full resolution images will give more details.
