Orthogonal moment-based descriptors for pose shape query on 3D point cloud patches

作者：

Highlights：

• New 3D Tchebichef moment shape descriptor for shape query of point cloud patches.

• New voxelization scheme achieving translation, scale, and resolution invariance.

• New simulated human pose shape dataset for performance assessment per viewing angle.

• Demonstrated that native 3D shape analysis is superior to 2D depth image analysis.
