What is it about?
The huge data volume of 3D point clouds hinders their widespread application, especially in virtual and augmented reality and autonomous driving. We propose an efficient generative adversarial network (GAN)-based compression method for point cloud attributes, which reduces the data volume significantly.

Why is it important?
Without efficient compression, 3D interaction between humans, machines, and virtual persons will be impossible, as the current network bandwidth cannot afford such a huge data volume. However, compression methods will also cause information loss, the reconstruction quality should also be guaranteed when designing the compression method.
