Salient Points Analysis (SPA) is an unsupervised learning based method for registration of 3D point cloud objcets. This is an official implementation of SPA by Pranav Kadam, Min Zhang, Shan Liu and C.-C. Jay Kuo. This work was carried out at Media Communications Lab (MCL), University of Southern California, USA.

In this work, we propose Salient Points Analysis (SPA), a method for registering 3D point clouds. The SPA paper can be found here.
