A method for representing 3D tree objects using chain coding
TLDR
This work describes a method for representing 3D (three-dimensional) tree objects by means of a chain code and obtains some tree descriptors of objects on real images, which preserves the shape of trees and allows us to know their geometrical and topological properties.About:

A new relative chain code in 3D
TL;DR: A new chain code to represent 3D discrete curves is proposed, based on a search for relative changes in the 3D Euclidean space, and an alphabet of only 25 symbols is required to represent any face, edge or vertex-connected discrete curve.

Proposing a new code by considering pieces of discrete straight lines in contour shapes
TL;DR: The proposed MDF9 code, introduced, gives better compression efficiency than existing codes and is compared with the six well-known contour codes for compression without loss of information.

Representation of enclosing surfaces from simple voxelized objects by means of a chain code
TL;DR: A chain code for representing three-dimensional (3D) simple objects is defined and the descriptor is invariant under rotation and translation, and some results of this code applied to large objects are presented and its convenience over other codes is demonstrated.

Valence Normalized Spatial Median for skeletonization and matching
TL;DR: By integrating a robust skeletonization technique with 3D chain coding, the proposed algorithm can compare not only the skeleton topology but also the curvature of skeleton segments and measure shape dissimilarity.

Implicit Modeling of Patient-Specific Aortic Dissections with Elliptic Fourier Descriptors
TL;DR: The approach is a step forward to an automated generation of surface models for aortic dissections from raw 3D imaging segmentation masks and employs elliptic Fourier descriptors, which allows users to control the accuracy of the cross‐sectional contour of a flow channel.
