Center of Contour
|
|
|
Hi,
Could you please tell me what is the most efficient way of finding the
center of mass of the area enclosed by a closed contour.
I have a considerable circular region with streaks coming out of it in
either direction. Basically i want to find the center of the circular
region but it is getting offset due to the presence of connected
outlier segments.
I am working with binary images only.
Thanks a ton,
Soumyadip. |

Uh... What's the *C++ language* question here, again?

Good for you. Now, find a better place to ask your math question. I
can recommend to start in 'sci.math' newsgroup hierarchy.

As Victor mentioned, "sci.math" would be a good place to ask.
Also look-up "center of mass" in a calculus textbook.
Also try asking general programming and algorithm questions in
the "comp.programming" newsgroup.
Also try running the following search on www.google.com :
"center of mass" algorithm
Once you have an algorithm, and have implimented it in C++, if you
have problems with it, come back here and paste your code and ask
your C++ language questions here. :-)

If you have the contour then you can find the COM by integrating over
the boundary. |
