1. A system for mesh segmentation and mesh registration, the system comprising: a preoperative workstation operably configured to extract a preoperative anatomical mesh, from a preoperative anatomical image based on a base topology of an anatomical mesh template; and an intraoperative workstation, wherein the intraoperative workstation is operably configured to extract an intraoperative anatomical mesh from an intraoperative anatomical image based on a preoperative topology of the preoperative anatomical mesh derived from the base topology of the anatomical mesh template, and wherein the intraoperative workstation is further operably configured to register the preoperative anatomical image and the intraoperative anatomical image based on a mapping correspondence between the preoperative anatomical mesh and the intraoperative anatomical mesh established by an intraoperative topology of the intraoperative anatomical mesh derived from the preoperative topology of the preoperative anatomical mesh.
