I would like to track the position of people inside a space,

I tried by using the cv.jit Blobs centroid patch but it is not really reliable,

I would like to make the same thing as a movement tracking but when

people do not move the camera can still detect their position!

Is someone can help me please, I am quite stuck :s

Because it tracks to much elements.

 I have seen this work quite properly, but only because of very steady light conditions and a white floor. What you track really needs to stand out from the background. What you could anyhow try is subtract the image of the empty space from what you get in from the video, and use that for analysis. A more costly option is to use thermal cameras.

have to make some testing with the light,

If someone find another solution, let me know, :))

Thank you,
I also though it was a pb of lighting,
maybe there are some other way to do it,

Be sure to try the "threshold" attribute for cv.jit.blobs.centroids, setting this higher will filter out the many small blobs it finds. Also you can utilize only a certain number of tracked blobs by using [jit.spill] on the blob coordinate/area matrix, so if you only want 4 blobs, use jit.spill @listlength 4, for each of the 3 planes (X, Y, Area). This should give you the data for only the 4 largest blobs.
