Method, system and terminal for measuring shape dissimilarity of complex tree-like objects

Abstract

Disclosure relates to the fields of computer graphics, three-dimensional vision and medical image processing, and discloses a method, a system and a terminal for measuring shape dissimilarity of complex tree-like objects. The method includes: extracting skeleton curve information from a trunk of a 3D model of a tree-like object, wherein each trunk skeleton curve describes spatial position information and thickness of the trunk; representing the tree-like object using the trunk skeleton curve as a basic structural unit in a hierarchical iterative manner; categorizing the tree-like object as either simple or complex based on the number of layers; wherein, a simple tree-like object is composed of a main trunk and multiple side branches, a complex tree-like object is composed of a main trunk and multiple sub-trees, and each sub-tree is further composed of a trunk and multiple sub-trees/side branches.
