[#labelling] outputs 6 numbers per blob: area, y average, x average, yy 
variance, yx variance, xx variance. (the 0.9.6 version of the help file 
says deviation instead of variance, which is wrong... i just fixed it)

see the new help file:

[#labelling] does not give you a bounding-box (min/max).

You would preprocess the images so that the blobs to be extracted become 
white (1) on black (0) background. There are many ways to do this. you 
could look at color_detect.pd to get some ideas.
