Contour of a blob

[GoogleCodeExporter]

Hi Grendel
I need to get the contour of a blob (easy task)
but I need the contour pixels in some order (e.g. clockwise)
since I need to connect them by a line in another application.

I was wondering, if, by chance, you have a piece of code availble 
for this purpose.

Thanks a lot again
Best regards
Dan

Hello Dan,

I'll see if I can add something about contour in the library. I don't know how 
to
implement it right now, but I'll study it.

Regards

Truth to be told, I found an easy and effective way to get what I was looking 
for.
Once the blob has been identified via cvblob, it is possible to use open-cv
(cvFindContour) functions to get the contour.
Thanks so much as well.

Hello!

Although there is cvFindContour in OpenCV I have written my own functions for
contours. They are in the last version of cvBlob.

Only for information ;)

Hey, cvBlobs are incredible!
I would love to ask you, is there a way to convert your cvBlob contour into a 
standard OpenCV one? (vector vector point)
Thank you!
