A new relative chain code in 3D

作者：

Highlights：

• We defined new rotations to be used to propose a 3D code.

• Equivalent simple paths allow to save information to be labeled.

• We found that a set of 25 symbols codify any face, edge and vertex connected 3D path.

• We applied the new code to a set of skeletons and digital elevation model data.

• We found invariance under transformations and high compression level of the new 3D code.
