3D keypoint/interest point detectors and discriptors

Hallo,

I am doing a research in the topic of 3D feature detectors and descriptors for point clouds. I am supposed to use ready implementations in my application but I have noticed that there are no implemented functions or toolboxes for this area. I would like any help in the following detectors(3D point cloud as input ):

1. Local Surface Patches (LSP)
2. Intrinsic Shape Signatures (ISS)
3. Heat Kernel Signature (HKS)
4. KeyPoint Quality (KPQ)
5. Laplace-Beltrami Scale-Space (LBSS)
6. KeyPoint Quality-Adaptive Scale (KPQ-AS)
7. Salient Points (SP)
8. 3D-SIFT

Thanks in advance. I appreciate any help

Same question here, too. Did you get any solutions?

Same question, I want to implement 3D-SIFT descriptor. Please post here, if you have got any solution.
