Tensorflow implementation of Normal Distributions Transform
Normal Distribution Transform works. Test with python rosCloudToNDT.py The file publishes the resulting NDT's on ROS. A listener can then do the registration/visualization. https://github.com/azaganidis/se_ndt contains an example for visualization, but is undocumented.
Registration in tensorflow is working, but slow due to operations incompatible with cuda. Not recommended yet.
