c++ - Libraries or algorithms for blob detection in stereo images -

-

i looking way detect blobs in stereo-images have not been able find yet. want detect objects example people standing in front of camera , cut object out continue processing on blob without background. know libraries or algorithms blob detection / tracking in stereo images?

if can expect background static relative foreground try opencv background subtractor. there 2 versions based on modelling each pixel mixture of gaussians, constructing background model distributions persist longest (i.e. static). pixels can labeled foreground when values shift beyond threshold learned background distribution.
