Thanks for your nice work, but I have some questions about the code and PointSIFT.
First, in the section 4 of paper "PointSIFT: A SIFT-like Network Module for 3D Point Cloud Semantic Segmentation", the multi OE uint stacked to integrates multi-scale feature. However, in the code I did not find this kind of structure.
Second, the pointsifi_res_module looks like a two stacked OE uints. Is there any specific meaning of this desigen?
Third, I am confused about the code line 41 - 43 in pointSIFT_pointnet.py as they have same inputs and parameters. What's the meaning of this structure?
