Recognition of Point Sets Objects in Realistic Scenes

Figure 14

Robustness test. It can be observed that as the number of points in the input network decreases, the accuracy of the network on the test set becomes lower and lower. As long as the number of input points is greater than or equal to 64 points, the accuracy of the test set can be maintained above 80%. It can be seen that the robustness of the network is still very good.
