Motion Tracking cv.jit.

Hi

I´m working on video tracking for a dance performance. Basically its working fine, but i still have a few things to solve. May someone can give me a help.

I think one of my basic problems is, how to view data out of the cv.jit objects.
(e.g. cv.jit.centroids, cv.jit. blob.sort, ...

I tried with Jit cellblock and switching through the planes, but how to get them out of jit.cellblock. For example in the helppatch of cv.jit.blobs.moments. How do i grab the xy coordinates for any further use. Problably some very easy solution which i just dont get.

another thing:
cv.jit. blobs.sort + cv.jit.blobs.color are giving random colors. How can i stop this and adjust certain colors to certain blobs ? e.g in size order.
How can i get xy coordinates out of the colors ?

color 1 = xy
color 2 = xy
color 3 = xy
...

As a work around i was thinking about combining tutorial 25 with jit.blobs.sort.
it works fine with one blob and one color, of course. But not with more than one color. And i could not find the way to select a certain color in tutorial 25. ???

... and the question which is asked a lot in this forum, but i could not find an answer. How to work wich cv.jit.blob.sort ? How to get data from the sorted Blobs ?
Like index + xy coordinates ?

Sorry for too many questions, its because i m thinking of several ways to get to the goal.
i would appreciate any help. ... feel free to choose the question ... :)

Thanks
