Environments: Ubuntu14.04, ROS indigo, opencv 2.4

I would like to do scalable object detection.

Do someone know where I can find the BiGG/BiggyPy source code or package to use?

There is no source code and steps about BiGG/BiggyPy on ROW wiki. http://wiki.ros.org/bigg_detector/Tutorials/How%20to%20train%20and%20use%20the%20BiGG%20object%20detector

Besides, does someone know which is the most popular and open source algorithm to do scalable object detection?

Thanks in advance. Any advise is appreciated.
