cv.jit is really a great tool but is there any object to extract the 
x,y vertices of the contour of a blob?
e.g. something similar to what you find in Processing with the JMyron 
or BlobDetection libraries (see

You could try something with cv.jit.binedge (or cv.jit.canny). It depends on what you want to do with the data.

If you don't mind coding up some C, I have an unreleased and half

finished object that uses OpenCV to get the contours of blobs in

vector graphics form. Let me know and I can post it.

all these produce pixel-images, not x,y vector lists.

it is true that all your shape analysis objects provide a large 

toolset to make shape pattern analysis/recoginition; but it is useful 

in many cases - analysis and processing - to have a vector based

Thanks!

i will need some time to learn to set up the environment and the
